You have to work very hard to make a faith centred on Jesus, his words and actions, into this religion… and they do. I have watch firsthand how much effort goes into the indoctrination that allows churches to make christianity into this awfulness.
Worth noting that so many leading abolitionists were followers and ‘friends of’ Jesus, and that they explicitly said that it was that faith that lead them to put their lives on the line for the cause.
