I'll be fair, there was a thread recently, aimed at Christians, and I posted in it... but it kind of made me cringe.
But other than that, there's some heated rhetoric from both sides in the political section as well as debates. There are certain Trump-supporting Christians here who push back. And some of us Democrats, both Christian and non-Christian, push back too.
Here is my whole problem though:
Around the 70's-80's, under Billy Graham and others, there was an evangelical movement started within Christianity, promoting anti-abortion, ideas involving theocracy, etc. Some people didn't like it, but I saw it as pretty mild and supporting as many good things as negative. Afterward, about the time of Trump, things got complicated. It's like, the evangelical movement put all their weight behind Trump, and even changed some of its ideas in support of Trump.
As for my advice on what to do about people who are hard on Christians on RF. It's hard to say, but whether or not you support Trump, I have my serious doubts most people are talking about you when they speak of "Christians". They're talking more about activists of McCarthyism. Who exist both on the forum, and are ready to participate and fire back, sometimes firing the first shot - and also exist in real life.
