I do not think Rachel "boycotting" Letterman who have made any point whatsoever. She would have just been a guest who was never booked. Accepting the invitation then lecturing Letterman on taste (or tastelessness) would have seemed impolite and wouldn't have accomplished a thing either. I watch Rachel daily for all the stories no one else covers, if her being on Letterman expands that audience. More power to her. The NYTimes would not have covered the Kill the Gays Uganda Bill had she not brought it to the attention of the world. I say put her on every show she will do. We'll all be better off because of it.
