What's so Christian about red and green? Because it's for Christmas? Last time I checked, the red and green with Santa and reindeer and all has nothing to do with Jesus.
Actually, I don't think the red and green comes from Santa and reindeer, MG. There are a couple theories, most of which are pagan and/or deal with the winter solstice. Most of everything that has to do with Christmas is pagan and has very little to nothing to do with a Abrahamic God, anyhow.
I was always under the understanding that Christians borrowed what used to be a pagan holiday to celebrate Jesus' birth and that his actual birthday would have been somewhere around October.
Jesusmas is an evolution of the Roman Saturnalia festival. When the Christian church was converting more and more pagans to Christianity, the masses didn't want to abandon their 12 days of orgies and feasting. So the Saturnalia became Jesus's birthday celebration, and that's how we got The Twelve Days of Jesusmas.
Begin the airing of grievances!
