One of the reasons I stuck around the lemmyverse is the diversity of political leanings, with a pleasant lack of fascists. I think my own political leanings have become more left since I've been here, and some threads make me question long held beliefs. I see this as a good thing.

As is the case with most online communities, there is a very vocal minority. Users can block/ignore other users and I think that is a better option than defederating.
