From what I read in comments, lemmy.ml is often associated with reality-detached far-left/socialism/fascist-socialism. People often call people from there “tankies”.

Personally, I don’t like how it’s often voiced prejudice instead of taking the comment at hand. Still, subjectively, I also saw several instances of far fetched and non-sensical stuff from lemmy.ml and maybe another instance as well, moreso than from other instance’s accounts.
