OP, you are simply one easily-triggered individual. This stuff happens between teams all around the country at nearly all levels of the sport, this sport and others. I could be seriously idealistic about this, but my opinion is that if fans, themselves, started to behave a little less like complete asshats, maybe it would trickle down to the players on the field. Maybe. But a lot of the "unsavory" cultural aspects of sports are in no small part due to fan behavior.
Used to be all kinds of shit-talking occurred and it was mostly mutual-respect fun in nature, thus all the video content out there of old hats in various sports waxing nostalgic about who was the best trash talker, obviously enjoying that part of the game. Now, seems like a different thing altogether. Seems like guys, fans included, act like complete assholes knowing that at least one target of their crap will respond in kind, thus justifying their own behavior.
But, yeah, this shit is everywhere and I'm not going to single out Iowa State for it.
