I don't have a problem with any ALUF's being Ute fans - sports is sports, and it is separate from religion. I do think it's odd (wrong, maybe) to hate BYU and want it to fail if you're LDS, even outside the context of sports or in areas that BYU is getting good publicity for the Church (like with Jimmer). Not saying all LDS Ute fans are like that, but they get caught up in it sometimes.
Your post about whether someone can be a good LDS member and still sit by someone who smokes or drinks is way off base. Nobody is saying that.
