This is just like spending a bunch of time with religious zealots trying to convince them their religion is wrong. You're wasting your time, and you're just going to create more conflict. I have one Trump supporter in my social circle and when conversations veer that way with her it's never productive so I completely avoid it.

The bottom line is you cannot use logic to convince people their religious beliefs are wrong. Most rational people already know this about religions and religious people, the problem is they don't realize that right-wing politics (or any extremist politics for that matter) is also a religion.

Now before you try to argue that this only applies to the extremists, the problem in this country is that the entire right wing in this country is extremist. The only non-extremist position in this country is the mainstream Democratic party, which is basically center-right. The Republicans have gone full-on hard-right, so there's just no reasoning with anyone that buys into that stuff.
