Defense of faith always carries the risk of being ridiculed, so that’s not a big problem. But just to state the truth, belief in the sprit of Christmas is not stupid. It might be to you, but it’s stupid to get in and ruin it for kids.
Sorry, I meant to ban stupid people who are bothered by anything Christian. Anyone with speck of intelligence knows that Jesus was sent to save us, we even calculate our calendar based on His birth Anno Domine - 2014 AD.
