I unfortunately do think they're a real person. Ironically, if it was an LLM I'd actually expect it to engage with the content of my comments, respond to logic, and write something that at least on the surface seems coherent and thought-out. Not this guy though.

Their tactic seems to be intentionally misunderstanding something you said, then forcing you to defend a view you don't even hold - all while never ceding an inch no matter how many logical errors, misunderstandings, and false assumptions you point out in their responses. I believe they're just highly ideological, and the moment you make the kind of noises their imagined enemy would make, you get labeled and treated as such.

I honestly kind of hope they're just a troll, because at that they're actually pretty good. If not, then it's kind of worrying to think how someone ends up at that point. What they've demonstrated here is a near-perfect example of insane troll logic.
