Crusaders were Christians. Spanish Inquisitors were Christian. Nazis were Christian. KKK were Christian. MAGA is Christian. There seems to be a pattern here...
I mean, if it was a one-off maybe there would be a good argument but at this point, don't we have to be honest that there has to be something wrong at the root? Being a Christian is like a dice-toss. Maybe you come out like Bishop Mariann Budde or maybe you come out hating gay people and thinking they should all be unalived.
There is no way in Hell I don't believe in that something that can lead to such wildly different outcomes, outcomes that lead to extreme suffering, is also a universal truth.
