@Parentofachild You have been asked multiple times, but you still haven't explained.
Why do you want to withdraw your child?
Are religious beliefs presented as "Christians believe X, Muslims believe Y" or is there indoctrination, are certain religious beliefs presented as dogmatically true, etc?
I see nothing wrong with exposing children to various worldviews and religious beliefs. If anything, showing them how beliefs differ, how many religious beliefs are patently contrary to British values (eg opposition to same-sex relationships), etc etc etc is unlikely to produce religious fanatics.
Or, on the contrary, is your view that you do NOT want your child exposed to other worldviews, and want your child to be taught that whatever YOU and your church believe is true, that everyone else is wrong and will rot in hell, etc? If that's what you want, you live in the wrong country, I am afraid.
How old is your child? You do understand that they have the right to make up your mind and have a different opinion from you in matters of religion and morality, right?
