For me, it’s the lack of diversity in opinions. IDK about you but I’ve only seen people from here and lemmygrad.ml, and nearly everyone is pretty far left. I’m not having a big problem with it, but the site is very, umm, single-minded.
And this mind is particularly hostile to my ideas
I mean true but I wouldn’t say it’s so black and white. Sometimes there are amounts of disagreement, and sometimes the entire site/group/something things exactly the same way.
Although this has much to do with the type of site you’re on and the way submissions are ordered. E.g. where they are ordered by the number of replies, then more inflammatory submissions will be at the top, while a vote-based system (most of social media today), benefits the most popular opinions in said community
