I’ve wondered for awhile what it would look like if they managed to succeed in a religion-based takeover of the USA. I figure the dominant force in the world’s varieties of Christianity being Catholicism would have some influence (and since the Pope has more money than God) so it’s entirely possible that the “one true religion” ruling the country would end up being Catholicism and there would be a lot of really disappointed Protestant fascists.
EDIT: also I was thinking that’s the more likely result as the majority of SC justices are Catholic currently
