NOTE: Many people on this forums are non-Christians, so you may offend some of them so not to be creating a religion war here.
Not necessarily. I'm not Christian but I still have a Christmas tree and lights. In fact many non-Christians do celebrate Xmas...just not religiously.
by the way, Merry Christmas and Happy Channukah
