My wife has been cursed, criticized, and demeaned by BYU fans. She no longer goes because she doesn't want to put up with it. I don't blame her or anyone else who doesn't feel welcome.
Check some of the threads on here in the past. Complaints about old people, kids, women, wearing wrong colors, being too fat, voice too high-pitched, yelling too much, not yelling enough, standing too much, sitting too much, smelly food, spilling drinks, kids crying, getting bumped from behind, people in front leaning back too far, people constantly moving in and out, etc.
I'm a season ticket holder and I have thick skin and can handle humans. Not everyone can and society is becoming less and less able to tolerate being around other humans. I'm really not surprised at the dwindling numbers around the country.
That being said, more people will come and pay for the experience if you...
Just. Win. Baby.
