Are the majority of Utah fans not LDS? I guess I just assumed since Utah as a state is heavily mormon that there was a large number of mormons that were Utah fans.
Not as many are LDS as you would think. BYU in Provo is 95% Mormon, plus there are campuses in Hawaii and Idaho so those draw a lot of LDS kids.
The non-LDS kids would tend to go to state schools more. This site says the U of U is about 35% Mormon.

In addition to attending to ISU and transferring to BYU as an undergrad, I got my master's from the U of U.
But I was married, owned a house and just commuted for the classes. It was much less of a "college" experience vs a "job", so I don't really feel a tie to their athletics program. I personally didn't experience much, if any antagonism, toward LDS people. Which is a credit to the U. Maybe sports are different.
Edit: Apologies to Dr. Wardell. He was a great and definitely the most "Mormon" professor I had at the U. And a huge Utah sports fan. It just never stuck with me.
