"Jesus is the reason for the season."
Actually, no he isn't. According to the data in the Gospels, Jesus was born in the spring, early fall at the latest. The celebration of Christmas was a circa 400 AD (AKA CE) move by the Church to try and co-op pagan Yule festivals and the celebration of Apollo's birth. As a result the leaders of the pre-Catholic church decided to manufacture a celebration around the birth of Christ and schedule it to roughly coincide with the assorted Yule festivals.
Christmas trees, (Which may be forbidden by Jeremiah 10:1-5) the gift exchange, most the symbolism in Christmas decoration, even Santa Claus, are all Yule trappings. Jesus was clumsily grafted onto the existing traditions like a massive gold cross sprouting out of Stonehenge. A Catholic Saint was eventually tacked onto the Santa clause figure as an "origin" even though Santa predates Christ by 3,000 to 4,000 years. Comic book fans call this a retcon.
In the end, Christmas has very little to do with Christ. If you stripped away all the pagan trappings you'd be left with an extra church service Christmas Eve, another on Christmas day and a nativity. Unless of course the Nativity was stolen from the celebration of Apollo's birth. At that point you're left with the extra church services. Given everything else the church in Rome stole from the pagans, I wouldn't put it past them to have "borrowed" the nativity as well.
And don't get me started on the difference between Angels as described in the Bible and the winged androgynous sissies on Hallmark greeting cards.
