As well as a few bowl games for both teams. I have family members with season tickets to both stadiums and some of us wear blue to both places and some of them wear red to both places. We just haven’t seen any of what you say has happened to you. Sure there is the occasional foul mouth idiot or even the jerk in your face type fan. But it’s on both sides of the rivalry. I will agree Utah side there is more cursing and drinking that leads to a different level of trash talk. But I’ve also found that the way you respond to fan banter often dictates the results of fan banter.
I’m also not naive to think this never goes on, but sometimes if you look like and easy target or a less threatening target, I could see how some of these incidents like this could result. But multiple ones seems to indicate either shared experiences you are making your own, or you are involved more than you are letting us know about.
