All I'm going to say is that if you're going to keep Christmas a religious holiday, then keep it a religious holiday. Remove ALL pagan symbols from your home. Christmas tree included.
It's really important that we understand the history of Christmas. Christmas is so intermixed with ancient pagan rituals because the early Christians found it difficult to convert pagans to Chritianity. So by leaving some of the old pagan traditions more pagans converted. Don't even get me started that December 25th is also a pagan day...it's the winter solstice.
Now, Santa Claus's name is actually derived from the Dutch Sinter Klauss. Read about him here
