s'ok if I am. But threads complaining about this sort of thing are a regular MN feature, and I can't help thinking that some parents seem tremendously precious about it. We're Christians and it often comes up that not everyone believes the way we do, and I talk to my children about it and they wander off and scribble on the lounge walls again.
I've seen people complaining about Christian mums and tots groups, simple 'thankyou' prayers and christian charities. I am 100% ok with you bringing your children up atheist, theist, or chocolate-worshipping. Honestly, if I whipped myself up into a panic over every mention of different beliefs or none that my children encounter, I'd never get anything done.
(Please note, this is not a church schools whinge, I'm against selection on religious grounds.)
