In light of our society trying to wipe out Christian influence from every aspect of life, from the display of the Decalogue to the blatant attempt to deny Christians a religious Christmas (but where your money is more than welcome) I am proposing a new holiday. A "Who-ville Christmas" to be exact.
Everyone knows the story of the Grinch. He also tried to steal Christmas by stealing all the decorations and presents, but found that even without all these things the Whos down in Who-ville came together and celebrated the spirit of Christmas anyways.
How is a Who-ville Christmas to be celebrated? On January 6th, twelve days after Christmas. Your celebration can be the exact same as your Christmas celebration is now. One change however is to focus on the birth of the Christ child on the 25th and not have presents until Jan 6th, and to avoid shopping as much as possible between Thanksgiving and Christmas. By avoiding shopping until Dec. 26th retailers would feel the financial squeeze because of the loss of Christian's money during the one time of the year they count on most.
As money is the one thing the world listens to, taking this action will quickly put a stop to the retail world trying to make this holiday into nothing more meaningful than an orgy of spending.
