Should we ban bad theology carols?

From CT:

“Only with great care. For thousands, carols will be their only link with a church. At the same time, sentimentality is perhaps the single most dangerous feature of our Church and culture—and the sentimental air is never thicker than at Christmas. The Incarnation is messy, dirty, and resonates with the crucifixion. We need a new wave of carol writing that can gradually swill out the nonsense and catch the piercing, joy-through-pain refrains of the New Testament.”
