A fair minded person would see that the predominant effect that all sects of Christianity has on the US these days is negative, and that’s largely due to the evangelical/Nationalist Christian wing. And sure; they might not be the numerical majority of “all Christians in the US”, but they are having a disproportionately large impact on the rest of Christianity in the country, as well as the country as a whole.
So sure: you can sit here and whinge all you want about how it’s unfair that people are becoming more and more hostile towards Christians because a subset of them are giving all the others a bad name (huh… where have we seen this dynamic before? Perhaps sometime in the early 2000s, in the context of a related but distinct Abrahamic monotheistic religion…?), but when an extremist sect does evil shit and the rest of the denomination does pretty much fuck-all to stop it, people are going to take an increasingly dim view of the religion as a whole. People don’t like it when you do shitty things to them. That’s just humans being humans.
Put another way: I’ll stop pre-judging Christians in America as hypocrites of the highest caliber once they can get their own fucking house in order, because right now it looks a distressingly large proportion of them are doing their level best to tear the fucking country apart in some nihilistic pursuit of hastening the end times so they can get raptured to heaven or some shit like that.
