After getting into an argument with several Jewish friends about whether or not the Christmas tree is a religious symbol or not, let's take a break and say, Chappy Channuka! Yeah!
Chanuka is a minor holiday in the Jewish religion. It's observance is noted primarily as a counterbalance to Christmas. Forget it, guys, you lose. Christmas rocks as a holiday. We got the red ribbons going, the bells, the songs. What songs does Chanuka have? I have a little dreidl? Oh please. Comes to music, Christmas rocks. And most of the most popular songs are secular, and NOT religious.
I maintain that the first holiday humans observed was the winter's solstice. Damn, the sun was dying and humankind would all die, then suddenly enough virgins were sacrificed and the sun came back. That's a reason to celebrate.
Call it anything you want: Christmas, Chanuka, Kwaanza, etc., etc. What we celebrate is the midwinter's solstice.
