For me it's categorizing radical ideologies correctly. I just hate people throwing around buzzwords, calling anyone a communist/fascist they disagree with. Those words have meanings. You can actually be worse then the fascists and still not be one, it's not impossible. You can still be hated for that, but you didn't automatically become one, because you are right-wing and coincidentally an asshole. But the moment someome calls you a fascist, while you're just an asshole, their opinon automatically becomes invalid and wrong.

I turned off vote display and rarely miss seeing the votes. See also Facebook Demetricator.

Yeah, it's the strange thing about engaging post titles - people seem to be so busy answering them, they 'forget' to also upvote them. In contrast, a meme that's funny but about which there's not much to say, is more likely to get an upvote as some kind of compensation for the lack of discussion.
