This is the point I’m trying to make. You can defend Gary Glitter’s song because it is about Christmas. It is not about how much he loves teen girls, or more accurately to the Cosby example, how much absolutely can’t stand people who do. That’s fine and understandable, and what I do with Rowling. My next thought, however, is if Gary Glitter is worth keeping around at all. Is a pop tune ever worth the trouble? It’s not for me, but that’s an actual opinion.
