@Misadventure I think there's a couple things. One is objective criticism. Certainly, some behavior is objectively fucked up. (I just read the Batshit Crazy Sightings thread today.) But more often, I think that someone gets upset at a perceived slight, rants, and the responses are subjective. Ideally, calling out behavior could be objectively discussed, and something constructive can come out of it.
Idealism, and 'boring.' I get it, well, I get that will be the majority reaction.
The other... if more people realized their shit stank too. The overall sense is that people are quick to shit on things, and not remember the times they were the problem. There's little empathy. But, see my mid point note. I get that's not the point.
Now, I haven't read much outside of the Hog Pit, though I'm starting to. And the more I see, the more I see the potential of what others have already said - A place for real talk, a place where people can't face retribution (well, not in game in theory) for their opinion, a way to see and discuss different perspectives. I will say it's fairly intimidating as a new poster.
