Yes, Christmas and Easter both have pagan origins. But that doesn't really matter if someone wants to celebrate Christmas as the celebration of Jesus' birth. What it should mean is that people stop getting angry with those who don't celbrate Christmas, or say Happy Holidays instead. People should stop getting angry at people for "taking Christ out of Christmas" because he was never in Christmas until the Catholic church established the holiday. Annual Christmas celebrations aren't in the bible, so no Christian is obligated to celebrate it. But there is nothing wrong with it either.
