But surely Christmas wouldn't be here without the birth, according to Christians, of Jesus.
As far as I'm aware we still live in a Christian country, regardless of whether or not you believe in Christianity, therefore it is, and always will be, Christmas.
It doesn't upset me Hindus celebrating Diwali, Jews celebrating Passover or Muslims celebrating the end of Ramadan.
I puport to being an agnostic, but will not support anybody or thing that tries to take Christ out if Christmas for fear of upsetting somebody else.
