It depends on lot on the sub and how their moderators police the community, but yeah, I've seen lots of that.

I've been aggressively downvoted before for pointing out facts that people don't want to be true. (And these were not even political discussions!) I don't even bother with putting my opinions online at any rate, both because they don't actually matter to anyone but me, and because I don't get any joy out of defending them against internet randos.

Edit: It depends on the size of the sub as well. I'm a member of a few subs that I can stand because the moderators are good at moderating, and there are enough regular users coming through to counter a small number of very active cranks.
