One of my half-sisters was raised in a fundamentalist church, and went to a school run by the church. She was taught science as the bible tells it. She was taught a curriculum that any YEC creationist would approve of.
She is a methamphetamine addict. She mainlines the junk. I do not expect her to be alive much longer. According to your logic, her fundamentalist Christian education is to blame. I do not agree with you.
Awful scourge in rural & suburban America (in places one wouldn't expect). Sorry to hear about your half-sister - my hopes and prayers are with her.
