Yes, I'm the same, when. I only mention my atheism on forums like this which are there to discuss such things. DH and I didn't even mention our beliefs when we exercised our parental right to withdraw DD from religious observances at her primary school. We simply informed the HT that we wished to do that. In fact, our action had a positive effect on religious education in the school (from which, of course, we did not withdraw her) because they expanded the curriculum to include religions other than the Abrahamic ones.
DD took part in Christmas and Harvest Celebrations along with all the other children because, as we pointed out, midwinter feasting and fun existed before christianity was invented, and so did harvest celebrations. Besides, they are cultural celebrations rather than religious ones for most people.
When she was in the top primary year, DD said she wanted to go along to the two annual church services that the entire school (except her, the school secretary, the janitor, and the classroom assistant left in charge of DD) attended. By then we felt she was old enough to choose for herself, and anyway, she only wanted to go so she could play her trumpet as part of her class's goodbye to primary school 'show'.
lily, the fact that religious indoctrination doesn't always work, doesn't mean it's not wrong. Some people are less susceptible to brainwashing than others. Thank goodness, or we'd still be in the Dark Ages.
