Writing in the Guardian, Dan Gillmor argues that SOPA and PIPA aren't foolishly extreme because their proponents don't understand the net; rather, they are extreme because their proponents understand that the net breaks the monopoly of the powerful over communications and organizing.
So, why do they make unsupportable statements?
Because they don't dare make an honest argument. If they were saying what they believe, it would go roughly this way: "The internet threatens our longstanding control of information and communications, and that is simply unacceptable. Therefore, it is essential to curb the utility of the internet for everyone else."
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
