Another quick note on the matter of the practicalities of speech-oriented boycotts:
It’s the Internet era. We’re moving inexorably closer to the day when you can’t shut anyone up. Ask Christopher Allbritton — not that anyone was trying to shut him up, but he’s a great demonstration of how much the reach of the independent commentator/journalist has grown. People who want to get their message across need big media less and less.
Right now, you can pull together a sizable interest group without media help. That’s a distinct change in social possibilities. You probably can’t put together an interest group big enough to matter in a national election, but the day is coming. Put differently: South Park got on the air because a little Christmas card video was distributed all over the Internet.
Those who want to influence the opinions of the future ought to be thinking about establishing the core mechanisms for person-to-person communication right now.
