Utah is also heavily Mormon, which complicates things. Mormons have a lot of beliefs that sound fairly socialist when you describe them in practice, except that they believe the church should be the administrator of those policies.
Mormons also heavily oppose abortion, which makes them a nearly single-issue voting bloc, making Utah deep red in a purely partisan sense.
If somehow abortion were a non-issue - like, overnight, everyone somehow magically forgot abortion even existed - it's not hard to imagine Mormons being one of the least conservative Christian denominations.
(Yes, I'm aware that other Christians don't consider the LDS to be Christians, but that's beside the point)
A lot of hardline religious sects superficially look like socialism if you only examine their in-groups and entirely ignore their out-groups. The Church of Jesus Christ of Latter-Day Saints is no exception.
You're getting downvoted, but you're broadly correct. There's a lot of research showing how more homogeneously white populations are more likely to support leftist or socialist policies (policies, not affiliation) than people of the same demographics who live in more heterogeneous places.
The key according to this article is the cost of housing, not implied racism.
