I like a few of these communities, and I've had some nice conversations on some things I'm passionate about. But it seems like the population outside my small communities is dominated by violent wanna-be political activists competing for who can express the most outrageous sentiment.
Advocating against violence against one's parents in a hypothetical situation where a parent developed the wrong US politics not only got me downvoted, but also replied to by some asshole from Australia who wanted to rub it in that I was clearly in the out-group.
I don't normally reply when I see things like that, but after seeing so much vitriol I felt the need to leave a comment. I won't be doing it again.
