I don't have a problem with people calling out the crazy shit in the Bible. I question it too.
I don't have a problem with people pointing out that people who identified as Christians and certain Christian based organizations have done heinous things.
My problem is with people that act like Christians are a monolith and try to attribute any bad act that any Christian has ever done to all Christians even when those bad acts are specifically against that tenets of the Christian faith. That's lazy and dumb thinking, and as
@King Freeman pointed out, it's the exact thing that racist white people have done to black people for decades in this country.
