I'm proud that we can debate without physical confrontation; higher-reasoning I guess. Think about it, if all debates where a physical confrontation it wouldn't be the best ideas that would win, but just those who are stronger would win.

Ok... So that's out there a bit. More on the lines of what you're asking, I'm proud that we realise it when we're getting out of hand and actually try to do something to alleviate the issue; philosophies of how to do that asside.
