Probably the most historically significant enemies of Christmas celebrations have been Christian conservatives. Under Oliver Cromwell's rule in England and under Puritan colonists in New England, Christmas celebrations were banned. In England, this briefly caused fans of Christmas, including those more sympathetic to Catholicism and the King, to engage in pro-Christmas rioting. It seems that these rioters were better than average for rioters, as all Wikipedia says about them is that they "decorated doorways with holly and shouted royalist slogans."
According to one historian, the modern conception of Christmas as a secularized family-oriented festival of gift-giving was heavily shaped by Charles Dickens in A Christmas Carol. This influential work was adapted into a cartoon by Disney in 1983, leading to Scrooge McDuck's starring role in the DuckTales animated series in 1987, and then the surprisingly awesome DuckTales 8-bit Nintendo game in 1989.
