The 22% might be non-Christians. I know a few people who celebrate the more commercial parts of Christmas (tree, Coca-Cola Santa) and are not Christians. Not the worst thing in the world as you can't celebrate Christmas, even in its sanitized commercialized form, and then be anti-Christian. Also, those people have no issue with saying "Merry Christmas" and think it's dumb that the mainstream culture seems to have an issue with it. Granted, they are not leftists. As a Christian, Christmas might be a good way to start a conversation with them if you think the might be open to converting.

On the other hand, no Christian should answer Santa Clause. St. Nicholas himself would have picked Jesus over himself in the poll. Hopefully no Christians are prioritizing the watered down commercial version of Christmas.
