The word "holiday" says it all. It is a holy day to celebrate something not of this world, something supernatural, like a saint, or the birth of the incarnate God. To think it is not religious is ridiculous. This is so twisted, just like all the propaganda from the atheistic left. So ugly. The parents should all quit the PTA and have their own meetings, and mostly, organize their own "holiday" party, with angels, and Jesus and the manger and Mary and Saint Nicholas. And Joseph, can't forget him. And, those so inclined should forage through the writings of the Founders, where they state the importance of religion in moral formation. Come on, guys, this is easy!!
