You're talking to a 49 year old German.
When I was about 15 or 16, I once naïvely asked my grandmother why noone resisted Hitler. She got very angry, told me I knew nothing about the time, and how much good Hitler had done, and then told me to shut up.
She suddenly turned from this loving person into a stubborn, old, bitter and aggressive woman, showed a side I had never seen of her. So she was a counter example to not one, but two of your claims:
- She was a real believer in fascism, and remained that even decades after the catastrophe fascism had plunged Germany and the world into.
- She emphatically was not pro free speech and would absolutely not tolerate me saying anything against her belief.
And she was a woman who claimed to be of a strong Christian faith. I'm well aware that not all of her circumstances translate 100% to modern day America, however I'm still inclined to think that most American Christian fascists also truly believe in both fascism and Christianity, just like my grandmother did.
In other words, I stand by what I said - "They are not christians" is a no true scotsman fallacy used to try and manufacture a distance between Christianity and fascism that does not exist. These people are both, Christians and fascists, and saying otherwise is a bad attempt to absolve religion.
