Apparently he was never taught how to reason logically, how to use and evaluate evidence, or how to think critically. He confuses feeling with thinking.
And one seems to severely undercuts their claim to be Christian when they support and try to justify the words and behavior of someone like Donald J. Trump, which so many on the religious right have done and continue to do.
"You are like the company you keep", thus if one supports autocrats that repeatedly lie, demean innocent people, repeatedly committing adultery, bragging how they can sexually assault women, bragging about their penis size, etc., they simply are not acting as a Christian would and must. Instead of Christianity, it's secular right-wing politics that's obviously their #1 driving force-- not Jesus' teachings of love of God & neighbor. And if Jesus was around today, I think he likely would tell them "I know ye not".
