I am a Christian, so I answered 'Yes', I celebrate Christmas, and what I celebrate is the birth of Jesus Christ.
As to Christian decorations, displays, etc. on public property, I have an interesting story. While back, I was having a conversation with my mother (who has VERY strong anti-Christian sentiments). She was upset b/c the schools were putting up "inspirational sayings" on the classroom walls. There were quotes from the major religions (Judeo-Christian, Muslim, Hindu, Buddhist, etc.) as well as from people like Ben Franklin.
My mother was furious, b/c she saw this as an attempt by Christians to "get around" the separation of church and state. She said it was just a sneaky backdoor way to put the 10 Commandments up on the classroom walls!
As a Christian, I thought that was ridiculous. But you know, if there had been some quote from a Wicca sect espousing Satan worship or what-have-you, I probably would have preferred taking them all down rather than allowing that up.
So, my answer is, as much as a nativity scene warms my heart, I'm OK with having it at my home and not at City Hall.
