With all due respect that doesn't quite wash coming as it does from a long term moderator on a religion and ethics forum.
I've always been interested regarding why people take theism, especially Christianity, seriously even though I'm perplexed that they do. That they seem unable to keep it to themselves makes it fair game for discussion: hence, here we are.
I seem to recall your concern over school pupils being involved in the practice of school nativities thus betraying the same attitude as I did in my ignorance, considering Christianity as a danger to be avoided.
I have always taken the view that acts of religious worship have no place in schools, and especially primary schools, but I have no problem with teaching religious awareness and political/social history relating to religion. In fact, just before the summer break, we had a letter from the school reminding of how we could exclude the kids from religious observances (Easter services etc) if we wish to do so, though in reality these tend not to happen during the school day.
I don't see religion as an intrinsic 'danger', and I fully accept that for many families who have a religious outlook their bringing up their children accordingly is what they see as being in the best interests of their own children. That they do so is none of my business provided that it doesn't extend into what happens in schools.
