First, I’m definitely glad my child is NOT in the California school system. Heck, my son’s public school literature book has a couple of stories from the Bible.
I don’t spend hours deprogramming my child. He is bright enough and has been raised well enough that he can separate much of the BS. That’s not to say we don’t talk about things; we do. But 2-3 hours every day deprogramming? Anybody who has to spend that much time hasn’t laid the proper foundation, IMO.
I probably spent 2-3 hours a month discussing school matters with my girls. I never once tried to ‘deprogram’ them however. What I did do was surround them with Biblical concepts at home, coupled with regular church attendance, so that they immediately saw through lies and half-truths without my having to left a brain cell. I created Christian adults, not robots, with free will and a strong Biblical background
