How many are aware that the Christmas tree is originally pagan?

In the book of Jeremiah, God specifically tells his people to avoid all aspects of Yule, the decorated tree is mentioned in detail, as it is pagan and thus evil. The majority of modern Christians profess to follow everything in the Bible as what they are to follow as well. So based on that, why do Christians have a Christmas tree if they know if it is pagan? Or do they even realize that is the case? Why if it was not acceptable back then is it perfectly fine today? God himself also said that he does not change ever so that would mean that either he wasn't telling the truth when he ordered his people to avoid those, or Christians have misinterpreted the Bible.
