> Perhaps you are an "absolute" free speech absolutist

Emphatically not, in the sense it's commonly used, but I think the distinction between "shunned by private individuals/groups/companies" and "prosecuted" is critically important.

I'm not going to go through all of these point-by-point, but as a couple of examples:

> - Swatting?

Inciting an action should be charged on the basis of the action and the probability of having incited it. Charge them with attempted murder. Also, fix the mechanisms that make it feasible for a person to too-easily call down excessive force on someone's home or office.

> - Yelling "Fire!" in the proverbial crowded theater?

Inciting a predictable panic that gets people injured should get you charged over the injuries. But also, the original version of that phrase was used as part of an abominably bad ruling restricting people speaking out against a military draft, so it's a bad example.

See also laws about fraud: the speech isn't the issue, the deception leading to swindling people out of something is.

Similarly, credible threats to commit a crime should be charged accordingly, not because of the speech but as prevention of an intended/planned crime. (With a great deal of caution, due to the balance between preventing it and the hazards of charging a crime that hasn't happened yet; Minority Report is not a blueprint.)

the problem with swatting is that the police are too armed and do no investigation when instead they can destroy stuff and kill people

its just fine to call the cops. its not ok for the government to act on it thoughtlessly.

if people had yelled fire in that swiss club, maybe more people would have survived the fire?

why shouldnt i be able to put on an elvis costume and a bad accent?

The things you are listing really arent a big deal, and to be bad, have to include something more than just speech, eg. commerce
