People on lemmy are taking the blue pill and thinking that the fediverse is wholesome, the fediverse is many things (mostly positive) but saying that we've got no assholes is a lie (OP did say that "the whole fediverse is wholesome ❤")
That was definitely a good start, based on my own experience. Just keep an eye out for the popular degenerates from there and be ready to block them as well. Blocking their community doesn't keep them out of the comment sections else where. Especially politics.
