I learned of their horrible fans literally decades ago. Not to mention, I have a whole side of my family that are large donors (over $1.5 million annually) to their athletics program. I am very well acquainted with them. I attended every home game while I lived there.
The only time I will ever cheer for any ASU team in any sport to win a game is if they are playing yewtah, ohio state (football), or if them winning directly helps BYU win the conference or advance in some way.
