The big issue will be shutting down the strident “war on Christmas” conservatives. This is one of their favorite talking points. But my solution would be to point out that by removing the outrageous retail marketing and exploitation aspect associated with the Holliday you’d be making it easier for actual religious minded people to focus on the biblical/Christianity aspect of Christmas. You might actually get support from staunch Christians for limiting the big business/retail exploitation of the birth of their savior.
