One of the traditions of college football is that rabid student fans will paint their face, and sometimes whole body, in school colors. So when some ASU students painted their face black (the school's uniform color for the last several years) for a college football game, one would expect that people would take this as an entirely normal event, an expression of school loyalty. One would NOT expect that people would immediately assume the face-painting was some sort of racist statement. I mean, really, you wouldn't expect the rules to be different just because the school's uniform color happened to be black, right?
Well, you would be wrong. In this hyper-sensitive world of people SEEKING to be offended, people got offended.
PS - when our Coyote's hockey team makes the playoffs, they have a thing called a "white out" where everyone dresses in white, face paints in white, etc. Next time they make the playoffs (which may be a while), I think I am going to be offended.
