I dont think many Christians even know what they are truly celebrating on Christmas now.
Its not the birth of Christ, if it is, they are making a total mockery of his birth.
The day has now turned in a commercial retail holiday, in which Santa Claus is greater than Jesus and these same merchants that dont care and probably dont even believe in Jesus have no problem selling Christians all sorts of junk, making them rich, and sending them into debt they will probably be paying off til the next Xmas, and all this sales on on the basis of a lie of Jesus birthday being Dec 25th.
Merry Christmas will probably offend or get a person almost fired from their job, and a nativity scene is almost pretty much a no now adays.
Christmas trees, Elves, reindeer, a fat man going down your chimney, mistletoe, and yule logs have zero to do with Christ and are all based on Pagan sungod worship, yet many Christians that claim the day is about Jesus for them, all have some or all of these symbols as part of their Christmas celebration.
Starting to think God probably hates our modern day Christmas.
