Now we are parsing words. This is a Christmas tree that we are talking about here. Also, by the way, I don't see any problem with a nativity display either. Big deal (and I'm Jewish).
This whole thing has gotten out of hand.
But a Christmas Tree is secular it does not matter what anyone calls it it's not a religious Symbol.
A Menorah and the Nativity is religious and yes it would be wonderful if we could display both as it would truly signify a wonderful message to the world.
