War on Christmas
The War on Christmas refers specifically to the controversy surrounding the celebration or acknowledgment of the Christmas holiday in government, media, advertising and other secular environments. Modern-day controversy occurs around the world, and stems from the holiday's significant annual role in celebrating cultural values in Western society. The term "War on Christmas" is often used to address the controversy.
As Part of the Culture Wars
Culture War is a term used to describe the swaying of what is acceptable in a society between culturally conservative and liberal. To that end, the War on Christmas is a major skirmish in that war. Each year, more and more secular progressives work to eradicate the right of major retailers to say "Merry Christmas" or "Happy Christmas" in favor of the more benign, and ultimately godless "Happy Holidays." When the retailer gives in, they are less likely to begin using the older terms again, and, in order to save moeny and time, will simply acquiesce to the will of the liberal protesters, saying "Happy Holidays" from that time on.
As is common, individuals with a tendency toward liberal ideologies will not see the War on Christmas as real, and may even deny that there is such a controversy.
