An analogy I like to use is that there presumably could be aliens out there that would like to eat humans. You could imagine said aliens landing on Earth and trying to eat us, and even imagine some argument among themselves that humans aren't smart, and thus can be eaten - something that we'd all obviously find issue with.
Now obviously animals cannot think of or cannot communicate with us that they do not want to be eaten the same way we could with another species, but I believe part of the responsibility of having any kind of power (whether intellectual or otherwise), is to take the utmost care of those who are somehow weaker than you. To do otherwise is to take advantage (might makes right), and that notion is disturbing.
In those terms, I have a very hard time justifying raising, keeping, and killing (and in most cases causing incredible suffering) to animals purely for our pleasure, when it is both entirely possible and likely more efficient for us to not eat them.
Basically, the only reason we eat animals today is because we've always done things this way. I do not mean to be offensive, as putting it this way suggests that those eating animals are wrong or doing evil, but instead I just think it is one of the many little things that we as society and individuals do without much thought.
Especially when you consider that plants are also organisms, many of which exhibit complex reactions to stimuli, signalling among individuals, memory, etc.
Besides, I don't know of a compelling ethical argument for why it's worse for one to eat things that are perceived to be more similar to oneself. There seem to be obvious evolutionary arguments for why such taboos would develop, but that's not a sufficient argument in my opinion.
> Basically, the only reason we eat animals today is because we've always done things this way.
That's a bit oversimplified, because it implies that the genesis of humans (or their ancestors) eating animals is simply arbitrary, an accident of history. But it's pretty clear that eating animals provided some massive advantages over not doing so, and later domesticating animals for consumption even more so.
We'd all obviously find issue with being eaten not because we think it's unethical that the alien wants to eat us (it's unlikely that the ethics question would even come up), but because we don't want to die, as an individual and as a species (I'm trying to say that it's NOT obvious that the issue we would have with such a scenario would have anything to do with ethics, not to make a judgement whether it's ethical or not). And so your argument looks like it's saying "we don't want it to happen to us, therefore it's unethical (for anyone to do that to us, or for us to do that to others)". I know you probably doesn't mean it that way.
Now, whether it's ethical to eat meat itself. As someone else have mentioned, I've always wondered where do you draw the line? Pigs and cows seem obviously out of the questions, but how about cockroach, caterpillar, corepod, hydra[0]? Event certain plants do sense distress signals when they're being attacked.
Do we actually know that it's possible for us, as a society as a whole to survive entirely on non-animal products, food or otherwise? Additionally, even if it might be just historical accident that we have a heavy meat-eating society, and another society that starts out without ever using animal products can advance to where we are right now and have a perfectly functioning society, it doesn't mean that it's ever feasible to actually switch to such a no-animal product society. In our terms, that would be a switch from not just from one programming language to another, but probably from silicon-based chips to germanium-bases chips.
Although that may be true for some people, myself and many people I've talked to have given it significant amounts of thought and simply not found a sufficiently compelling argument against it.
It seems unfair to suggest, and apologies in advance if this wasn't the intention of your comment, that people who eat meat automatically do so due to lack of thought rather than having considered the options and positively chosen it as a course of action.
That's not obvious. The will to live is strong everywhere, and that cows don't speak "human" isn't to say they don't have a will to live (not be eaten). Nor that we can't speak "alien" any sign that we don't have a will to live (not be eaten).
This all reminds me of: http://www.terrybisson.com/page6/page6.html
This means, for octopuses (octopi as a plural is incorrect; its Greek not Latin) its probably ok. They are born alone, are loners and meet others of their kind only to mate. So snack away!
I used dolphins in my example because of a curious behavior seen at an annual dolphin slaughter. The Japanese annually net dolphins in a bay where they like to congregate (the dolphins, not the Japanese). Every year some dolphins escape the net.
The next year, the dolphins return en masse. Why? Didn't the dolphins that escaped give some alarm - "Aliens with catchy stringy things will entangle you and drag you up to the bright place if you go there!"
No, they apparently don't. Either because they don't communicate very well (which speaks poorly for their intelligence), or they just don't give a damn about other dolphins. Either way - dolphins pass my snack test.
Even some of the dolphins that escaped, return the next year. Why? Maybe they like it! Maybe its some rite of passage to run the gauntlet, risk capture in the bay of death! Like some Klingon warrior ritual or something. Then hey! we're just doing our part!
Or, far more likely in my opinion, they're just not very smart.
If you're talking about abused dogs being chained up and not taken care of, you're right. That is unethical.
1. My dogs live a much longer, happier, healthier life with me than they would out in the wild. Their lives are orders of magnitude better here.
2. Have you ever shown a dog a leash? :-)

On the specific topic of Cephalopods, I think our highest moral imperative is to ensure the survival and continued evolution of the species. If that requires farming some, fine, but we may find the intelligent life on earth in the next two million years belongs to them. Breaking that branch of, either trough ignorance or gluttony, is intolerable.
I'm not saying that there aren't tons of people who are very healthy vegetarians and vegans (some of them healthier than they would be eating meat), but I'd just like to point out that it's not universally true that you can replace animal protein with plant-based protein and be healthy. Nutrition is a complex topic, and not all bodies behave the same when it comes to food.
Soy is obviously not the only plant protein. My current favorite is mushroom-based, but it is new, and industrial food doesn't have a good track record.
Perhaps and with great care a diligence. Ask anyone who has tried to body build vegan, getting complete ammino acids takes planing. All the reverted vegans I know say they feel much better now. And being a vegan can be more unhealthy if you replaced the meat that was in your diet with carbs/sugars.
It is far more healthy to eat a diet without grain/carbs IMHO if you are choosing one thing to improve health.
Want to be in fat burning mode (ketonic)? Done. Want to cure your type II diabetes? Done. Want to lower your blood pressure? Done. Want to raise your HDL and lower your triglycerides? Done. Want to lower your cancer risk (est. 60-90% of tumors can't run off ketone bodies, but require sugars)? Done. Want to have better dental health? Done. Want to have consistent energy all day? Done.
Based on everything I have read and learned it is my strong (but open to change) opinion that the natural human diet was consistent daily consumption of vegetables/leafy greens (esp. low starch ones), occasional fruit and occasional gluttonous consumption of animal products as community members made kills.
That is to say, I think humans evolved for a ketogenic diet (< 20 grams of carbs/day) and that is why it makes so many people healthier, independent of choosing to have a caloric deficit.
That may be true for some people who don't pay much attention to their diet, but it's not true in the general case. See: http://www.ncbi.nlm.nih.gov/pubmed/19562864
On the point of "sacrifice," animals aren't making one. To sacrifice something, you must willingly trade it for something else. (Though plenty of BBQ joints will suggest otherwise[3].)

(This is probably obvious to you already being a vegan).
I'm curious, when did Inuits stop being human?

It's so good even my kids love it! "More tentacles, please!"
Back on topic though, this was another good read. The debate about how to cook it was hilarious:
He insisted that there was an art to cooking octopus correctly. His includes a Neapolitan trick: a wine cork in the cooking liquid. Éric Ripert and Harold McGee dismiss this step as mere legend—to which Pasternack gleefully responds, “Éric Ripert is full of shit!”

Octopus is definitely on my menu.
Wanting to exterminate all the jews and maintain the superiority of some concept of an Aryan race is nazism. Grading the edibility of animals by our perception of their intelligence might be right or might be wrong depending on your moral/ethical framework, but I'm not sure there is any consistent worldview in which it actually is nazism.
In other words, your comment doesn't help the vegetarian cause, and maybe being a bit more thoughtful is a small price to pay to turn that around.
We're not talking about whether or not killing is wrong, but rather where on the gradient of developed nervous system-like behavior is it ethically okay to kill something. Many people have chosen a higher point on the gradient than you have, but that by no means implies that it's okay to kill anything along the full spectrum. You've simply chosen a lower cut off point than others.
Edit: I don't understand the downvotes for this. Nazism is not all about racial cleansing and gas chambers; it has a strong social darwinist component in general. The vegetarian/vegan group know they are better people for having made the decision to stop eating meat. There is no gray area: they are right and everyone else is wrong, as illustrated by the parent comment.
