I would love to know where you are from? Where you grew up? Where you live now? Not liking BYU football does not make them anti-Mormon, you realize that? You realize if you dislike ND football you are not anti-Catholic?
This should be a case study for how perception is warped based on hate.
I know you have seen bad Utah fans. We all have. They are the vocal, annoying and disrespectful minority.....they are loud. That does not mean 50% are anti. You can use that number to justify your hate.
