Earlier quoted context omitted.
Children aren't property. It's perfectly reasonable for society to take children away from parents. We do it for various forms of abuse. We obviously want to be careful, but I see no reason to allow 14-year-olds to get married off by their parents to adult men in their cult. Nor do I think it's okay to change that to the parents let their 14-year-olds get groomed for 4 years either.
Okay, but if they send their children to christian school (I'm actually not religious myself), is that too much indoctrination for you, or is it okay for people to raise their children with their own views and culture?
Schools that teach against known facts like evolution are a net negative.
