I think it is a mischaracterization to say that the holiday of Christmas has pagan roots.
Yes, the winter solstice was celebrated by several cultures that eventually converted to Christianity. Those celebrations would include customs such as using conifer trees to decorate, etc. Yes, this was all done in the religious practice that involves gods with YHWH not being one of them.
However, it is actually a stretch to go: Yule = Christmas = Pagan Holiday = God hates it.
If you saw someone named Steve at a restaurant sitting a table with his closest family and friends in which they were all celebrating Steve would that mean you would be angered if your family and friends organized a dinner party to honor you? Same restaurant. Same table. Same food. Only everyone is having a good time while honoring you. Would you exclaim, "No! This is wrong! This is a dinner party with roots in Steve's dinner party?"
I will say that the holiday Christmas with its practices, imagery, and traditions are found no where in the Bible. If I were a Christian I would be a Catholic and this would not concern me. Catholics do not subscribe to the Protestant/Reformationist Lutheran concept of Sola Scripture (Scriptures Alone). Christmas was adopted by the Catholic Church as a religious holiday. The Catholic Church has a rich tradition of considering and accepting extra-Biblical writings. So, it makes sense.
