I didn't say telling them about Moses was "brainwashing". In fact I feel that DS should know about the bible stories for historical and cultural reasons. He should also know about all sorts of faiths on the same basis. I had a head teacher at my private primary who was staunch CofE, we did the Lord's prayer every morning, sang carols almost non-stop and I enjoyed it all until I was around 14. I read masses of history and politics books (inspired by a brilliantly clever history teacher) and then I changed my mind about politics and religion. I read and read and devoured it all, no one stopped me. I had a choice.
I wouldn't dream of pulling DS out of RE classes, as it would single him out and make him into a freak in the eyes of the ever so holier than thou parents at his school. He is at a very white middle class state school. I would much rather he joined in until he is old enough to understand things more clearly.
I got all the logic and "balance" I needed in secondary schools, by my father and my excellent history teachers. My mum was a very spiritual Christian. I called the priest for her as she lay on her death bed in hospital. It is the best thing I could have done for my dying mother, it is what she would have wanted, not what I wanted.
I am incredibly flexible. I take DS to church for a few minutes whenever I can to light candles for her in church. I told him his grandmother (whom he sadly can't remember as he was a todder when she died) liked going to church and listening to the lovely music. He has asked me many times whether she is in heaven (a word he has learned at school), and I said "if there is one, she is definitely there".
I think I am incredibly flexible with my son for an atheist !
The thing is I was able to choose because no one "brainwashed" me either way. DS will also be given the chance to choose. Some kids, sadly, NEVER get the choice at all. That is the danger. I am with Dawkins on this.
