I'm not a Christian in the believing sense of the word, but I was raised in Christian culture. I don't think it would be too much to ask for businesses that profit from it to acknowedge "the reason for the season", as they say. Heck, even those of us who don't particularly believe can appreciate the message of Christianity and share the sentiment at Christmas. Even the faithful Muslims I work with are more than willing to toss out a hearty "Merry Christmas" at that time of year.
Exactly! That's what I was thinking, too. One of the heartiest "Merry Christmas'" I receive each year are from a Jewish co-worker in a different office. And he enjoys that I remember to greet him with a Happy Chanukah during Chanukah. And Happy Holidays and Seasons Greetings have a place, too, but not as replacements for Merry Christmas and all hints that the holiday has a religious aspect.
