Pretty sure the Christian Nationalist extremists opposing Trump are all further to the Right / Fascist / Theocratic side.
The Christians on the Left are generally among the mildest, most polite opposition, whereas the extreme Leftists are generally against Christianity as part of the "establishment".
But of course, MAGA insists on attacking all enemies as "Leftists" because they really want more ammunition against Democrats (whom they also insist are Leftists, although that's a wee bit inaccurate 🙄 ).
