SOPA is bigger than a sledgehammer... It's killing that same ant with a nuclear bomb.
Really, we better hope this doesn't come back up for consideration, because there's a real possibility that other countries could start blocking our traffic, which effectively breaks the "universal" Internet. Well, for the U.S., anyway. The rest of the world could just choose to route around us, and consider our networks to be unsafe for commerce.
Really, if I was consulting a client overseas, if they did anything media-related I'd encourage them to block traffic from the United States. This inconceivably ridiculous standard of legal liability (extending to foreign nationals on foreign soil) where executives will be taken to prison because their users shared illegal files is so totally beyond the pale that, if a customer is exclusively a foreign company with no business presence in the United States, I'd strongly encourage them to simply block all traffic from all known U.S. IP addresses rather than accept the risk.
Texas was invented by atheists so they'd have an easier time making fun of christians.
