Exactly what the title says, Christianity in all its various strains still stems from the horrendous old testament, and with all the awful shit that endorses, as well as with things like Calvinism and the general doomsday cult foundations in the religion, why do some people still act so charitably towards it? Christianity has proven itself to be a morally corrupt and oppressive institution at every turn. Or maybe I’m just too negative? 
EDIT Ok guys I get it this was rather reductionist, and I definitely was disregarding all the good that religious folks have done, and that religion has inspired people to do, but again over correcting into enthusiastic support for religion can also be problematic.
I have investigated the old testament. god supports horrendous things.
What I meant was that the whole point of Jesus and the new Covenant was to fulfill the old one and liberate humanity with a new law of love.
p.s. I don’t know if it’s super appropriate for me to participate in this thread though, I don’t want to take a space away from people who have been victimized by religious bigotry from venting about that or voicing valid concerns. There’s a time and a place to set the record straight wrt theology, I appreciate that it might not be this one.
