Board policy states no personal insults, period. That takes some getting used to, and I got some infractions for it, being I was used to more of a free-for-all thing.
The upside to that? Banning insults removes about half of conservative trolling. They've still got their conspiracy theories, but their raging is greatly reduced if they can't go off on insult tirades.
The downside? They go sort of passive-aggressive on you. Instead of saying "You're a child molester!", which is not permitted, they'll say "Libtards are all child molesters", which gets around the no-insult rule, being it doesn't insult a specific person. So you do the same thing back, all sides dancing around the no-insult rule.
Same as every board, it has more than its share of right-wing conspiracy theorists who want to tell us all about their own special bizarre universe. I think the mods are a bit too hands off there, being they should move most of it to conspiracy theory folders. However, at least you don't get banned here for the crime of destroying nutty right-wing conspiracy theories, which puts this board way, way above USMB. And that's all we liberals really need, to not be censored.
