Almost 15 years ago my sister gave birth to a son, and, feeling that it was the right thing to do, married the boy's father even though she had little in common with him. The marriage lasted for about 3 or 4 years, was full of drama, and came to an inglorious and bitter end.
They worked out a joint custody arrangement where my sister had the more parental responsibilities of seeing to his education, but his dad still got to see him a good bit of the time.
A few years later, his dad married his current wife, a true-believing Pentecostal woman if ever there was. He soon joins the church, and without consulting my sister starts taking my nephew. The church that they belong to is very high-involvement, with scheduled activities almost every day of the week. Also, from what I can gather, the church is very clannish and of the fundy "We're saved/you're not/you're going to hell" variety. They are ready and waiting for the Rapture to come.
Now my nephew is getting close to the age where he will have more of his own voice in custody matters. And he is getting a tremendous amount of pressure from his dad to reject his more secular-minded mother (who according to him is unbelievably selfish for working a full time job instead of being a stay at home mom, however he didn't complain so much when they were married and she basically put him through school). The sad thing is that my nephew is *totally* buying the religion. He is heavily involved in this "Bible Quizzing" competitive thing, begs to be home-schooled, the whole works. He tells my sister that he hates her and wants to go live with his dad, mostly because at dad's house it is playtime, all the time, and very sheltered from the bad non-Church people.
I could go into a lot more detail but suffice to say that my sister's ex is a self-righteous asshole who treats her with zero respect. I don't know where I'm really going with this thread, I'm just really sad over this because it is tearing my sister up. She feels that she has already lost the battle for his mind to the fundies, and that when he becomes an adult he will cut off all contact with her. It's really sad, what Republican Church Nazis like them do to the unfortunate non-believers who happen to get in their way.
I think that Pentecostal Megachurchism makes JWism look tame by comparison. And I'm pretty sure that I've lost my nephew to it.
