there are long standing radicals on the .ml instances, to be sure. I would place the bulk of the current lemmy.ml userbase between Democratic Socialist and Social Democrat (with a strong, vocal splash of authoritarians mixed in there somewhere).
lemmygrad.ml and hexbear are often otherworldly - interesting to watch, ocassionally interesting to engage, but always entertaining if you can pick out the salient arguments from the confusion. love federated systems :-)
jfc, not this vampire again.
