LDS v Non LDS that can't be had directly in polite society. It's a little silly because so many of the U's alumni are LDS and BYU has non LDS fans. Furthermore, most LDS BYU fans would love to have great relations with those who are not of our faith. Some, like I suspect is the case with our friend Buzz Hunt, don't want any positive interaction with the church or its members.

As someone in another thread posted (I believe a BYU fan who is not of our faith), some in Utah go so far out of their way to shown they "aren't Mormon" that they become a caricature of themselves.
