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?
