/r/atheism often got cyberbullied for being a bunch of insufferable jerks.
I don’t believe in god but you would never find me any closer to hanging out in /r/atheism than any other actually religious subreddit.
I mean, I guess I don’t want to judge that much because of how a subreddit like that can be a place for people living in extremely oppressive/conservative christian communities to express their anger at being in such a suffocating environment, but it often seemed like the criticisms of religion from the sub were more of the “but akshually this part of believing in god is dumb” instead of more along the lines of “who cares if god exists, y’all are incredibly hateful”.
