Here is a link to a movie fromt he history channel that I think is quite good. It isn't trying to come against Christmas It actually assumes support of Christmas by it's audience, but the first 3/4 of the movie goes into the origins of Christmas and other symbols of Christmas and even mention the unliklihood of it being Messiah's birthday. At the last part it basically says how the Church gave in and rejoined celebration of Christmass after 200 years of outlawing it. All the original Puritans who came over from England outlawed this Pagan and unruly festival. There are many interesting facts I didn't even know about it's history. What is nice about it is because someone like the History channel is doing it you can give it to christians and they will be more likely to accept it. Though the movie doesn't condemn it it is actually better because they are more likely to accept that it's roots are to mithra, and paganism. I only hoped they would of mentioned more of the nimrod connection to the tree, they didn't go back far enough on that symbols history. Great tool to buy and share during the season.
