Christianity.

I was raised in the Methodist and Baptist churches and had a series of experiences in my teenage years that made me question it, then once I went to college, getting to experience the wider world convinced me that what I'd been taught was bullshit. I actually named my YouTube channel 'Sacrilegious Heathen' because I once asked a televangelist about how god could allow certain things to happen to kids and he told me "That's sacrilege. You're talking like a heathen."

That said, they're very, very good at programming young people and I had an ingrained fear of spiritual warfare that took me two years to get over. I even de-baptized myself because ritualizing my deconversion helped me put that period of my life behind me.

I still begrudge my parents for it, TBH. There was a wealth of experience I missed out on as a child and a young man because I was afraid of angering god, and I'll never get to the opportunity to have that again.

Pisses me off.
