Although I'm not a Christian I did send my dd to one. There were several reasons for this, among them was bullying by other children and her teacher. She was interested in the Christian faith and I wanted to encourage it.
It was the worse thing I ever did
She completely went off Christianity. She learned that women were second class citizens, while boys seemed to get away with anything girls were corrected on every thing. Including when she said someone had stolen her pencils and was reprimanded for making such an accusation. Yet when one of the boys handed them over - all broken - the teacher said nothing. 'he apologised for accidently breaking them'. What all 8 of them?
When she started wearing a training bra and the boys picked on her she told the teacher. The teacher told her to stop wearing the training bra and getting the boys into trouble. I wrote to the HT on that one asking for advice. IE what were the guidelines, were they based on age, cupsize or the maturity of her male peers.
I think the final straw for me and her was when the parents got up a petition to have her removed because she had the audacity to say humans were animals belonging to the mammal family.
Sadly my daughter learned early on that while individual christians can be wonderful people as a group they can be small minded and intollerant of others.
A friends daughter who went to a CofE school was booted out of the door as soon as she finished her exams for getting pregnant. Up till that point she was being encouraged to go to sixth form, but any offer was immediately withdrawn as soon as they found out.
Personally I think it was the best thing to happen to her. She travels for two hours to get to college one day a week and works in a hair salon four days. She is a great mum and works hard to provide for her child and to get a skill so she can support herself and her daughter. It is much harder on her but I honestly believe she is much better off where she is now.
In both cases while based around a church and Christian ethos they accept children who are not christian or go to church. In my case I actually paid for the privelage of my daughter losing her faith
The second one we went to view when dd was looking for a secondary school. I was not impressed with the way they spoke to parents, let alone the children.
I am sure there are good ones, but personally I'm not impressed by them.
