I didn't like attending BYU (I left voluntarily after three semesters) and I don't particularly like the institution as a neighbor in Utah county. I think some of the things it does reflects poorly on the LDS religion.
I wouldn't say I hate the University, but I certainly can understand why some good LDS members do.
I grew up going to BYU football games and I have been a ticket buying fan for a couple decades until this year.
I'm a definitely a fan of Football and very lukewarm about the University itself.
