lemmy.ml is good to avoid not only for political reasons but people that are nuts enough to defend genocide for countries they have on their team are not to be trusted with much anything else either. Users are cultists that politicise, brigade and harass and community mods on lemmy.ml adopt old school Soviet style silencing of thoughts and discussion other than the state approved.

Before you are making assumptions, I’m a leftie and have been for longer than most of the users there have been alive, but I’m not an authoritarian communist so apparently my thoughts are dangerous for the believers to hear.

Wherever you have your account you can block other instances and everything from selected domain names. My Fediverse experience is so much better after consequently filtering out everything lemmy.ml on every account and instance I’m on and I’d recommend it for everybody.
