Yes, but most people reading his book are considerably less important (at least, for my purposes) than people watching Laurence O'Donnell when he spends five minutes next week making fun of Glen Beck's book. Or Maureen Dowd's column when she does the same. Obviously if this is just a few pages in a little noticed book there is no problem with it at all (it's basically neutral). If Beck decides to spend a lot of time talking about it, to the point that it becomes identifiable as "one of Beck's ideas", that would be bad. I don't have a well-calibrated idea of how much publicity Beck gets these days or how often he puts out books which is why I'm unsure of the effect.
