I want EVERYONE to be better than the nastiness. I want people to be gracious in defeat and in victory. I want people to not lose sight of the opposition's humanity, regardless of who the opposition is or what the issue in question is.

I respect the urge to vent/gloat (and there are private contexts in which doing so is okay), but a system of "They did this bad thing first, so I'm gonna do it back to them" never works out well.
