unlike many here, I'm not about being right or any superiority

But also?

but seeing the plethora of downvotes I got I didn't even wanna bother

Most people can't even conceive that a term can be applied to something when the definition fits (and it does),

So you don't care about being right or "superiority", yet down votes upset you. And you don't care about being right, or trying to convince people, yet you keep making unsubstantiated claims that attempt to address people's rebuttals.

then there's you dumb enough to think I said Autistic people have an easier time there (I just said it's an autistic culture, that's absolutely not the same thing)

That's not what that person was claiming. They were stating that if Japan was truly an "autistic culture", actual autistic people living within that culture would have an easier time socially integrating with the society. Since this is not reflected among autistic populations in Japan, then it weighs against your original claim.

guy that went on an history diatribe on the origin of Japan, while explaining the origin doesn't change what I simply stated.

Lol, that was me. And it appears you still don't understand the importance of the context. Your claim was that Japan was culturally autistic, and extrapolated that this was due to their self imposed period of cultural isolation.

My rebuttal was that Japan is not "culturally autistic", but that the cultural irregularities you spoke of were the inevitable results of a rapid transition to the fascist imperialism that took place during the Meijji restoration.

I explicitly told that person that I wouldn't engage, but they still get surprised and try to high road me when I don't properly engage.

No, you kept making claims without any supporting evidence. Your entire mode of discourse is constructed from a logical fallacy. You really need to look up "Appeal to the Stone
