I would never attend BYU...it wasn't for me. But I don't hate the institution, much less the Church. Just trying to point out that not all (certainly not most) people who attend the other Universities are dying to go to the Y. It's just not for everyone.
Also, you people are just flat out crazy if you equate hating BYU sports to hating the Church. Take a step back from this and realize that it's just a friggin game, and it is normal to hate rival teams in any sport or league.
