I really think it all comes down to our unrealistic-mistake-shaming culture. Nobody wants to be wrong and belives in the voices in their head over what society asks. We watch sports just to shame mistakes. Following 2000-year-old ideas from nomads (aka most religions) and always adjusting it to be correct for the modern age is another perversion. At what point are you a human over being an american? At what point are you a member of a political party over being an american?
Trump is an extremely selfish person that serves himself first, family second, and political party third. America is just a talking point. Religion is just a talking point. It should be no surprise how his logic works and why American as a whole is messed up.
