To be honest, that is part of the home court/field advantage. These guys are big time college athletes getting their education (and probably more at UAT) paid for. That is all part of the game. They have to have thick skin and mental toughness. The game ain't for sissies. I know it seems classless, but the players probably can't even hear it or it doesn't bother them. If it does bother them, they may want to pick a different sport.
As far as the fans go, as long as there are not racial slurs or bad language, I'm good with them hammering any opponent (not just UAT) and being as ruthless as possible.
