Tolerating differences -- and yes, I realize it's not the same context -- is part of the point of this conversation. There are a lot of different interests. Not everybody has to share them all. Not everybody has to participate in the ones that are available.
A lot of talk has lent toward an interpretation that a stronger hand is all that's required for everything to get better. The problem, though, is that everyone has a different idea of what 'better' is, and what that stronger hand should be doing (if anything).
I like having an outlet where I am not forced to be civil. I am not always civil, and neither is anyone else. Sure, some people couch their harsh attitudes behind pretty words, but that doesn't change the reality of those attitudes being harsh; a serious personal attack or slight can be made in very pretty and formal words and it makes it no less a serious personal attack; a polite slap across the face is still a slap across the face.
I strongly believe that if the outlet in which we're not required to be civil to one another goes, it's highly likely we'll see considerably more of the above. While people think they're getting away with shit when they do those things, they're really not, because people do notice, and pretty words don't obfuscate nastiness very well in a hobby often focused on the creative use of language populated by folk generally far more literate than average. That brings the entire place down, from my perspective, because the folks doing this stuff? Already think that's civil and appropriate behavior, when really, it's genuine Pit fodder (read: it's not civil, respectful, etc.) sans profanity.
I want to see less of that shit outside the Pit, and shit is an accurate descriptor of these behaviors. I want to see more people willing to say, "Hey, that's not cool," when people act like this in areas that are supposed to focus on respectful dialogue and the exchange of ideas.
Removing the outlet for impolite dialogue isn't going to make the uncivil behavior go away. It's going to ensure it spreads in the form of even more 'fake nice', verbal sideswipes, ugly implications, holier-than-thou bullshit snootbaggery, and so on, because the only way to actually remove incivility is to remove it from people. Nobody's figured that one out yet, unfortunately.
