I can't find the original post, so I can't give you reasons for the negative reception. Maybe you made it sound more like a theory that the community deemed as nonsense? I have little to go off of here. But I agree that the subreddit can be a bit of an echochamber.
I had deleted it myself because of the situation escalating, so I couldn't find it either. The post in question was a headcanon about Annie possibly having autism.
Drama quickly stormed over, with users making comments like, "Just because you have autism doesn't mean that characters are autistic," or "Why can't a person be shy without autism?" Autistic headcanons are actually very common across social medias like Reddit, so that's why I made that post.
It wasn't me trying to diagnose Annie with random disorders, it was simply a set of ideas that helped me relate to the character as an autistic. That is exactly why autistic people make these kind of headcanons. But alas, I forgot that day that it was Reddit, where people overreact to anything.
P.s, I want to apologize for misunderstanding your judgement when I opined on Once in a Lifetime. I was tired when I made that itch.io post, so it was poorly organized and thought-out. I may not have 100% enjoyed the game, but I will admit that I still enjoyed several parts of it, like the darker storylines and plot twists. It turns out Rebecca was really good at teasing Charles, and I just misunderstood it at the time. The Carla relationship is complicated, but all acts with her were consensual at the end of the day. Charles matures a lot during the dangerous parts of the game. I also poorly read your social cues, a recurring problem of mine. I could have responded better.
Thank your for aplogizing! I can give you my perspective: I never heard of autistic people imagining fictional characters as autistic as well. So depending on how you worded your post, when you consider everyone who read it, there might actually have been more reasons to downvote than reasons to upvote, and hence the net result was negative. My guess is that you should've articulated your intent better, but I can't say for sure as long as I didn't see the original post. Either way, negative reception can hurt, but don't let it get to you too much, okay?
