I only avoid discussions with the hardcore leftist anarchist/communist groups because there is a big overlap between those communities and absolutely brain dead moderation policies.
Comments that have been removed/gotten me temp banned from Lemmygrad and .Ml include:
“millions of people died under Stalins rule”(banned, “misinfo”)
Someone commented “nuke Texas”
I said something to the effect of “yes blow up the 49% of Democratic voters”
-comment removed, comment calling to nuke Texas left up
Having comments edited by bots and mods so you don’t hurt anyone’s fee fees
There are other examples if I go through the mod log. Lemmy.Ml in particular takes an absolutely wild amount of mod/admin actions compared to any instance.
Tl;Dr: yes but not because of politics, because Lemmy leftists are the fucking worst
