While I agree with you about there being obnoxious and embarrassing U fans , there are BYU fans who are just the same. Both sides of fans have people who are out of line and whether it is blamed on anti mormon sentiment or BYU fans claiming superiority in righteousness becausse of their Mormonism, both are guilty. To put a blanket Statement out like "the majority" is just the rivalry in you. It would be naive to think other wise. I think anyone from either side would be wrong to say a fan from their repsective fanbase has not "Crossed the Line" at some point.
