Xmas is not leaving Christ out of Christmas. In fact, it is the exact opposite. "X" is an abbreviation for "Christ" because it was the first Greek letter of Christ's name.
Constantine's vision that resulted in his conversion to Christianity included the intertwining of the Greek letters, "Chi" and "Rho." We would see them written as an "X" and "P." Because they are the first two letters of the Greek word "Christ," the abbreviation of "X" for Christ, or sometimes "XP," has been used for many centuries.
How this modern idea that it was leaving Christ out of Christmas came along, I don't know. But it is a falsehood that upsets people greatly so every year I persist in pointing out the facts. People have enough stress in their lives. Please don't pass that along and add to it. Instead, take a moment to share the truth with those who do.
Instead of wasting energy being upset about something that is nothing to be upset about, we could do something Christ might do if he were still walking the Earth. We are commanded to take care of those less fortunate. Here are some organizations that I think do a great job of that:
