If only it were that easy.
I am one of those oddballs discussed in the first few posts who is both educated and religious (though I’m not a paedobaptist, so no funny looks from me about not baptizing your kids). I would be considered to be theologically conservative. I obviously have a completely different worldview from you (and most posters on this board).
But I’m also not part of the “religious right” because I try my best to take what Jesus said seriously. So there’s a lot of elements that go along with Republican politics or even just a “right wing” worldview that I cannot abide: pursuing wealth above all else, not taking care of the earth, the idolatry of American nationalism, the use of violence…I could go on and on.
More fundamentally, I don’t believe Christians should pursue worldly power, because we are called to serve rather than to use force. It’s antithetical to our mission and the methods we should use. I agree with you that Christianity should not be the basis for law; I believe in the separation of church and state. Not only because I don’t believe in coercing you or others, but because I’m concerned with protecting the church, too, whether from questions about whose version of Christianity is enshrined in law (“I’d give the Devil benefit of law for my own safety’s sake” as Moore says in A Man for All Seasons), or from becoming corrupted in pursuing power and destroying its witness…which, you know, look around. That ship has sailed.
I have been in a position to talk about this with others, to speak on it publicly, to write about it for well over a decade now, to audiences made up largely (though not exclusively) of Republican types, because I’ve been concerned about this from the Christian perspective long before Trump was ever a thing. At best, it’s treated as a sort of eccentricity of mine; at worst, it gets people angry (mostly because they agree with the premises, and then refuse to accept the conclusion).
Basically no one is receptive, because their worldview isn’t really Christian, either. They worship the flag, they think America is God’s Chosen People-look even at the language of soldiers making a sacrifice, the “altar of freedom,” the capitol as the “temple of democracy” etc. The earliest Christians died rather than burn incense to the Emperor; these people would like to have the State punish those who don’t stand for the national anthem.
You can’t show people that “your religion shouldn’t be the basis of law for everyone” when that IS their religion.
