I humbly propose that all Christian freepers start writing it as CHRISTmas, and even pronouncing it with the long I, as in Christ. It takes a little practice but soon it will become habit.
My whole family does it now. I always hoped it would spread into a nationwide phenomenon.
The X in Xmas is the greek letter chi, which represents Christ. Also, the X is a cross and this cross/X was the symbol was used by early Christians (very early) to secretly identify to each other that they were Christians. This was back when Christians were persecuted. We may need to save this X and use it again the way things are going.
