All these people with their panties in a twist about whether we say "Happy Holidays' or "Merry Christmas" are really giving me a rash. In fact the very word "holiday" is a reworking of the words holy and day. "Happy Holy Days" it seems to me would be no less honoring of the Spirit that Christ left on earth for all of us than is "Merry" Christ Mass. "Merriment" doesn't exactly evoke visions of "peace on earth, good will toward men" for me. It seems that it sort of feeds the flames of eat, drink, and get drunk, in other words, forced fun.
(Old English mæsse, from Church Latin missa, ultimately from Latin mittere to send away; perhaps derived from the concluding dismissal in the Roman Mass, Ite, missa est, Go, it is the dismissal)source: Wikipedia. I believe this dismissal is, or should be, an admonition to go forth and live the light of the Holy Spirit.
Neither Muslims nor Jews dispute the greatness of Jesus. Gandhi, a Hindu, spoke about his admiration for the ways of Jesus, and his use of Jesus example in his peaceful protests. Even atheists, if asked, would probably not want to go back to a world without the gentling aspects of the truly Christian way.
Rather than complaining, let's start a subversive protest. Many movements take root because they are sneaky and subversive, like early Chritianity. Would anyone object if we went back to saying "Happy Holy Days?" And how about wishing each other a Happy Christ Mass because we are going out into the world with the joy of the light of the Holy Spirit revealed to many of us by our Christ? With both, we can acknowledge the specialness of the new life breathed into the world by the introduction of the Ways of our Christ's life, not just the ways of his cross.
