because I went to a Catholic Convent! That works lol

But I think other Christian Schools maybe had the Nativity Play - not sure, except that if now they say only 1 in 5 puts them on in schools in UK then they MUST have been prevalent before the State Schools became so multi-cultural.

I still don't understand why it would be considered offensive (self EDIT: Why am I even using the word 'offensive' in relation to this?) especially if the parents want them to continue. The other children don't have to take part, just join in with the Christmas parties, same as ours do with THEIR diwanis and eid parties.
