... Generally, one of two things tend to be worshiped around the Christmas season. Either (per faith) it is Christ, or else (per secularism) it is self. The first is infinitely preferable, but neither one entails worshiping the Christmas tree. Not that such a thing is theoretically impossible (and I knew a secular guy who got a tree so big he couldn’t even get it into his house without cutting it further down... pretty good effort for a Selfmas), but we’re barking up an empirically inapplicable tree here. That doesn’t help the worship of the Lord at all.

Selfmas I love that! Self is the major idol of mankind.
