My brother lives in Vegas and is a Rebels fan. He is technically Mormon but probably would not consider himself one. But we went to the game together and overall had a great time.
After the game as we were walking out, there were several times when UNLV fans got in our faces and yelled your typical "Yewt the Mormons!" and trying to act like they wanted a fight. Finally my brother had had enough and he started telling back that he was Mormon, too, and telling them all to leave us alone.
Only time I heard him acknowledge his status in our religion. In s way, I'm grateful that it all happened.
