It’s one thing to have differing views, but I’ve seen enough attempted reddit migrations to be relieved that the popular communities in the fediverse so far haven’t been about crazy racist stuff or other extreme right bullshit.
I am also glad that I’m getting away from reddit’s general political shitposting, which was more left leaning. You couldn’t have any proper discourse on there, and even I with my generally more left leaning views recognized that.
One major feature of IRL conversations that keep them more civil than online ones is that the downvote button can be a physical punch to the face.
Though granted, this does mean that sometimes IRL conversations can become far less civil than online ones once that button gets pushed.
