fans I know have seen the behavior of the worst part of the fanbase during the BYU game and they've refused to go back to RES when BYU plays instead of trying to clean things up. Most of them will get tickets at LES when the yewts play, and they'll come dressed in red and cheer for the yewts but they refuse to go to their own stadium because of the crassness of a portion of their fans.
Didn't someone once say that all it takes for evil to thrive is for good men to do nothing, or something to that affect? If the good fans would all demand things to clean up it would, eventually but from where I sit it seems to get worse.
