Fuckk I'm not autistic to my knowledge but I feel this so much in online interactions especially and it's so confusing. I'm usually trying to contribute information or just have a conversation and people often think I'm trying to argue (I guess because presenting new information automatically = dunking or being argumentative somehow) and I've ended up just not wanting to interact much or I preemptively try to phrase things as questions (like "isn't x" or "I thought y") and it's so exhausting trying to do that all the time and it makes me want to crawl in a hole and not interact with anybody.
Reddit wasn't even always like that: I'd say it progressively went downhill during the last decade. Design choices were progressively made to tailor the most toxic users.
The other guy phrased it humorously, but yeah, that's Reddit culture. Particularly, lemmy.world took in lots of people from there and unfortunately, they never recovered. I've considered just blocking that whole instance for that reason.
