I don't think they're against atheism. It's just the stereotype that online atheist communities tend to be insufferable, and, I'll say it, holier than thou.
Where I see most of the "toxic redditisms" is in political communities. So far I've been blocking them as they pop up on my feed, and it makes the experience much more enjoyable/cordial.
What an idealistic and utopian view. A sovereign country has been invaded, it has the right to use weapons it deems necessary to defend itself. What's so difficult about that? Russia can pack up and go home, then there will be peace.
For some reason my entire account is being mass downvoted, anyone else have this happen before?
