It’s going to be Evangelical. Some variety of megachurch prosperity teaching that faults the poor with some kind of republican ideology.
That’s why anyone that believes in separation of religion and state should tell these folks anytime they push for Christianity in schools, just tell them: ok but it needs to be the true Christianity- Jehovah Witnesses- then they will shut up. They hate Jehovah witnesses, then Mormons, then Catholics, …
At this point, it's going to be some sort of post-Christian, culturally Christian social media influencer-driven, conspiracy theory-laden melange that incorporates everything from Tartarian giants to simulation hypothesis to Flat Earth. Q Gospel indeed.
It stuns me that Republican Mormons think that Evangelicals like them for anything but their political assistance. As soon as Evangelicals remove the non-Christians, their tent will get smaller, just like you're saying.
I have Mormon family that thinks that they're welcome in the Evangelical tent (they'll even visit the Ark Experience!), but Evangelicals hate Mormons just like they hate gays, liberals, trans people, atheists, etc. It's just that Mormons (for now) vote the way that Evangelicals want.
