Thanks, all. Here is the email I wrote to UNLV's athletic director. I'll let you know if I get any responses.
"Mike,
Although I am well aware you have no control over the actions of individuals, as Athletic Director for UNLV you do hold a very public position and are hence able to sway public opinion. Consequently, I am writing to you to let you know how dumbfounded I am at the behavior of UNLV fans at the MWC Men's Basketball Championship game.
I am certainly in favor of spirited, competitive athletic events and even the celebratory rushing of the court or field, but violence and derogatory yells and signs toward a particular religious group are an entirely different matter. I hope at the very least you publicly encourage UNLV students to abstain from such behavior. I, as well as many others I know, will not be attending any more UNLV MWC hosted events."
