I’m not American, but as far as I can tell, it’s also not universal among American Christians. Obama is not like that at all, and he’s a Christian. (And from my perspective, he’s a lot more Christian than any Republican.) It’s not even true for all Evangelicals, because Jimmy Carter was evangelical.
It’s just that Republicans try to paint the image that to be a Christian, you have to be a self-righteous hypocritical bigot, and too many people are buying into that narrative. Please don’t.

Original sin does not require telling a 2 year old that they’re a terrible person. Quite the opposite: Christians tell their kids that God loves them. But that we are sinners is hard to deny when you look at the state of the world. And even the best of us fall short of what Jesus expects from us, but we should try anyway. To love our neighbour, feed the hungry, shelter the homeless, welcome the foreigner, and even love our enemy. Nobody does all of that to the level that we should, but we should try anyway.
But clearly there are people with a more negative approach to this. I think they’re a bit too eager to prove their own point of being terrible people. We should strive to be good instead.
