It seems to me that it is neither the progressives nor the pluralists who are the reason that “Christmas” has become a “Holiday” but rather it’s the capitalists. In an effort to extend the season, business has had to work to make the season less specific to a religion and appeal to as many people as possible.
Politics and economics get conflated and confused. It just happens that the agenda of business appears to be the same as progressive or pluralist agendas, but the purpose and desired end are completely divergent.
So, the “Christmas Warriors” should really think about taking steps to rescue Saturnalia from the capitalists who have secularized it in order to appeal to the widest possible audience of consumers for the greatest period of the calendar possible.
But, if you want to get down to it, the romans stole from the etruscans or somebody the holiday that became Saturnalia fair and square centuries before it became associated with what has become modern Christianity.
On a serious note, this is one of those places where it seems to me that the conservative political agenda appears to be contradictory in it’s support of both crass commercialism / corporatism and conservative / fundimentalist religion, two things I do not think mix and I’m inclined to disagree with independently anyway. This would be something that I would have to sit down and discuss with someone that held those views.
