You might find the Ad Hominem Fallacy Fallacy page interesting:
"Argumentum ad hominem is the logical fallacy of attempting to undermine a speaker's argument by attacking the speaker instead of addressing the argument. The mere presence of a personal attack does not indicate ad hominem: the attack must be used for the purpose of undermining the argument, or otherwise the logical fallacy isn't there. It is not a logical fallacy to attack someone; the fallacy comes from assuming that a personal attack is also necessarily an attack on that person's arguments."

So for example, if I said: "The arguments for constructing an AI pause button are bad because they are being made by AI company employees", this would be a fallacious argument.
If I said: "HN users have this weird mental block where they fail to take AI progress seriously", that's not necessarily a fallacious argument, unless it's for the purpose of undermining an argument the HN user made.
You have only an extremely weak basis for this claim and have essentially just made it up.

Posts reaching the front page is not a reliable way to measure what "most people here" believe.

It's not irony.
