The following is a quote from the great Ben Stein -
..."am a Jew, and every single one of my ancestors was Jewish. And it does not bother me even a little bit when people call those beautiful lit up, bejeweled trees Christmas trees. I don't feel threatened. I don't feel discriminated against. That's what they are: Christmas trees. It doesn't bother me a bit when people say, "Merry Christmas" to me. I don't think they are slighting me or getting ready to put me in a ghetto. In fact, I kind of like it. It shows that we are all brothers and sisters celebrating this happy time of year. It doesn't bother me at all that there is a manger scene on display at a key intersection near my beach house in Malibu. If people want a creche, it's just as fine with me as is the Menorah a few hundred yards away.
I don't like getting pushed around for being a Jew and I don't think Christians like getting pushed around for being Christians. I think people who believe in God are sick and tired of getting pushed around, period. I have no idea where the concept came from that America is an explicitly atheist country. I can't find it in the Constitution and I don't like it being shoved down my throat...."

Because of my personal experience with Christ, knowing him as a Savior, Sovereign Lord, Father and friend, I wish that everyone would have the joy of that experience. So I want to wish you a merry Christmas, regardless of your knowledge of Christ thus far...it isn't shoving my beliefs down your throat, it is simply my WISH that you would know the Joy that comes from knowing God, the Father and his insurmountable love for you, manifest in his son Jesus.
