Utah fans have different religions, they drink, some don’t, some use drugs, most don’t, some have pre-marital sex, etc etc. Basically they reflect America and society as a whole.
This is a generalization, but for the most part LDS people spend most of their time with other LDS people. Places I have been where I had LDS classmates, most of them never really hung out with us or joined us for parties, etc. They were mostly viewed as weird or strange. Once again, this isn’t true of every LDS classmate, I had some really cool social ones that fit in really well with our classes as a whole.
