I was thinking about this issue this morning. Christians think they they have compelling evidence that their religion is true, and they just need to convince us nonbelievers of this evidence and then we'll start going to church (plus whatever else they expect/want). However, providing actual evidence that their god is real isn't enough, and I don't think they grasp that. Let's say that Christians are able to provide actual good evidence in this area: I would start believing their god is real, but I wouldn't repent or start worshipping him because their god is a genocidal monster.
In the end, it doesn't matter if their god is real, because we'd all be under duress to worship him just to avoid an eternity of torture. It's garbage. I'd rather suffer for eternity than worship a god like theirs. But they only think about the first hand of the problem, and many of them deny that their god is malevolent.
I am like you! My dad_loved_Rush Limbaugh. But I was raised nondenominational. Became a Calvinist for a little while, worked at a Christian summer camp. Then got my first job at a U-Haul where my coworkers mostly POC. I met my future husband there, who helped me see how fucked up my upbringing was. Honestly it's been twelve years and I'm still uncovering shit.
But yeah, change is possible, just difficult. It's difficult to leave your tribe because they're fuckwits.
