I think political communities in general tend to get quite heated if a debate gets going and because it’s unlikely people are going to change their mind it gets personal.

In some ways the left wing ones are worse for this - I have been accused in my time of being too left wing and too right wing, there’s a lot of different splinter groups and factions.

Tbh I just avoid politics on Reddit, Lemmy and similar, unless it’s just to share or comment on a news story maybe. I don’t think it’s the right format for reasonable conversation
