If you're Christian, merry Christmas!
If you're Jewish, happy Chanukkah!
If you just want to be with your family and share the joys of the holiday season, happy holidays!
Finally, if you believe we athiests have declared war on Christmas, read Michelle Goldberg's column in Salon, then Frank Rich (reg.req.) in the New York Times, then reflect on why any majority group in a democracy, who control the government and the press, would persist in believing that the minority were oppressing it.
