"It isn't the purpose of my post, but I personally believe religious and cultural traditions are mainly the responsibility of a child's family to teach, not the state education system."
Either you don't have kids OP or, as a member of the majority faith, are simply too privileged to be able to see past your own nose.
Kids spend more awake time at school than they do at home and it's important for them to see their culture and religion reflected in their teachers and peers. So he doesn't have to feel awkward explaining why he's eating "crackers" in March/April instead of sandwiches or - like I was at primary school - accidentally given pork sausages.
And given that it's CHRISTMAS CHRISTMAS CHRISTMAS on TV, shops and, yes, school from December 1st to 31st me celebrating Chanukah with my DC for 8 days just can't compete. At least a faith school rebalances the scales a little bit.
Your bitterness and privilege is overwhelming.
Oh and for all the smarmy clever clogs going "you should have looked into what 'non denomination' means snigger" I was using it as a loose term meaning "not faith based". It was a regular nursery. Most nurseries aren't faith based. They still spend all of December focused on Christmas and all of March/April focused on Easter.
Which, as I said, is fair enough, I respect I live in a Christian majority country but to then take away my options to be able for my child to experience, in a school community setting, his own faith and culture seems extremely unfair.
