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.
