Much has been written about the War on Christmas, started by Oliver Cromwell and reported by Papa Bear. Honestly, it's a load of crap. How would a Christian feel if they had "Happy Hanukkah" shoved down their throats and giant menorahs decorating public lands? They would feel outraged, and demand a stop to it.
To me, Christmas is about spending time with loved ones, good food, lots of gifts, going out in the snow, seeing those I haven't seen in many months, and generally having good times. Whether it be Hanukkah, Christmas, Festivus, or any other of the numerous holidays celebrated at this time of year, it is what it is, a Winter Solstice holiday, celebrating the ending of one year and the beginning of another. Everyone should be happy we live in a culture where we can take off work, practice gluttony, and give gifts away, because it could be a lot worse. So what if people don't say "Merry Christmas" on the street?
