Although it originally did not have anything to do with the birth of Jesus Christ, but until it was continuiously celebrated as the point in time when Jesus Christ was born, it stands as a dedication to remember what gift was given to the world.
(I'm going to leave out the fact that without Christmas there would be no record setting sales for department stores and an appropriate reason to even recieve gifts from family members, significant others, etc.)
Its been a long lasting tradition since roughly the 4th century, and what reason is there that justifies changing it now?
However, being the Christian that I am, my opinion is that yes it is just another ruthless act to try and restrict religious freedoms within the United States by anti-religious groups. Offensive ? Yeah. But im not a radical, however it seems as if I should be in this situation.
