For all their “christianity”, republicans in the US are pretty hypocritical.
Jesus actually teached that everybody deserves to get fed and housed. That everybody deserves healthcare. That people should care for other people in their community. That is essentially the core principles of socialism.
Christianity is incredibly easy to fake. Anyone can call themselves a Christian with little, if any, blowback. It’s the whole ‘sinner saved by grace’ schtick - which is, essentially, “Yup, I’m a Christian but I don’t really have to act like one.”
