Non-Mormon in Utah. I grew up here. In high school, I felt excluded. I felt like all the social activities centered on the Mormon Church, and I was left out. I resented it, deeply and for a long time.

Eventually I realized: Maybe it was just because I was a nerd. Maybe it wasn't the fault of the Mormon Church at all.

As a non-Mormon, I haven't been unwelcome anywhere, ever. There still is a bit of a feeling of being an outsider, but it's not like "no promotions for you" or anything. I've been treated fairly everywhere I've been. (Disclaimer: I'm male, white, straight, and cis. I don't know enough to speak for the experience of those who are not.)
