Well in my world, I know of no one who is forced to practice religion, or to think Christianity is the only or true religion.

Where I live and I suppose the rest of the UK one can choose religion or reject it, personally I think there is good and bad in religion, but the good certainly outweighs the bad.
I know a few atheist/agnostic families where one or more of the children have turned to a faith based life and some devout families who's children have rejected religion.

I think perhaps you have got the whole issue completely out of proportion, obsessiveness can eventually become a serious problem when there is nothing to reinforce it.
It is surely all a matter of personal choice, after all, "faith" is not about to make anyone ill?
