The Trumpers want the US to become a theocracy
It happens in Islamic Theocracies, not in modern secular states.
Some of their politicians are openly calling for the US to become a Christian nationalist nation. They aren't even trying to hide it anymore. That's exactly what the Islamic hard liners did - the ones who eventually took countries like Afghanistan from being a secular state to being a theocracy.
There is little doubt that if the Marjorie Taylor Greens were running the US, we would have the Evangelical equivalent of Sharia Law. No access to contraception, let alone abortion. At least not for white women.
Non whites would be second class citizens, and deported if they committed any crime even if their family had been US citizens for 100 years. Gay/Trans people would be rounded up and placed in "re-education camps", and those who couldn't/wouldn't pretend to be straight would essentially be caged up there for life.
It would be seen as the duty of white women to have children, so white women who chose to be (or were through no fault of their own) childless would openly be discriminated against and called a race traitor. A white women having the baby of a black man would be imprisoned.
You probably think I'm making all this up, but this is all in the writings that these people follow. This is the goal of people like Steve Bannon and Steven Miller.
