Does Reason Injure Spirit?

From No Reason for the Season by Torie Bosch:

Most of the classic songs and movies that celebrate Christmas don't even mention God or Jesus. Santa doesn't check church attendance to decide whether he's going to give a child a present—he checks whether she's been naughty or nice. He's the perfect secular judge of moral fiber. To say that the secularists injure the Christmas spirit is much like the claim that two men getting hitched will besmirch the sanctity of marriage. Why should the way I mark Christmas bother anyone?
