[Disclaimer] - I am not an American and I consider myself atheist, I am Caucasian and born in a pre-dominantly Christian country.
Based on my limited knowledge of Christianity, it is all about social justice, compassion and peace.
And I was always wondering how come Republicans are perceiving themselves as devout Christians while the political party they support is openly opposing those virtues and if this doesn’t make them hypocrites?
For them the mortal enemy are the lefties who are all about social justice, helping the vulnerable and the not so fortunate and peace.
Christianity sounds to me a lot more like socialist utopia.
So, there is a lot of history here, but basically back in the day, there was an extreme sect of christanity known as the Puritans, and they were basically chased out of England, facing religious persecution and ran to the (at the time) new colonies in North America. This underpins why there is a separation of church and state in the US, but also why an above average number of the christians over here are insane.
