I think it's silly to deliberately avoid watching a program because it's controversial. At the very least, you get to see first-hand what people will be talking about. At the most, you'll be inspired to research the program and separate fact from fiction.
I don't know how networks know how many people are watching their programs. Is it extrapolated from the Nielsen data? Anyway, you could always have someone record it for you. Chris has a tv card for his new computer; I could ask him to save the show and burn it to DVD so you can watch it on your computer. Or, chances are, someone will post it on YouTube or Google Video or whatever, too.
