as your brain cells have likely already closed up shop on this one.
The information about the guy being banned was reported in the news. And was also mentioned previously in this thread. It wouldn't even have taken research on your part - just reading comprehension.
I am one that would tell a knuckle head to stop their behavior. I'm also one that if I noted someone that was known to be banned in the stadium I would report it. There are way to many stadiums in the world each and every year that have some random fan run on to the field past other spectators and security to say BYU allowed it to happen like 64K fans and BYU administrators wanted it to happen. There is a reason why even if the person is just being a nutty fan they are treated harshly by security when they are caught (even at BYU) - you never know what their intent is.
You can continue with your rose colored glasses and calling me out all you want it doesn't really bother me. I don't think anything I've said has been holier than though or self-righteous.
You must have your head in the sand if you think only one Utah fan has ever flipped off a BYU coach/player/fan. So good luck with your hate and continuing the tradition of Utah fans/admin by not taking any accountability for the yahoo's around you.
