Those are people not actual respected information outlets. If you just listen to people and do no research on your own, your an idiot to begin with but at the same time if one side doesn't use the sheep the other will so I'd rather have half the uniformed public thinking congress wants the internet turned off than them siding with congress.

For US sites: You're not going to see and indefinite blacklist where you can use a proxy to get to the site, you're going to see that for a period of time and then the site will go down if it does not remove the content and pay various fines. Its likely that most blacklisted site will never return or be accessible for but a short period of time.
For Non-US sites: You are correct because they won't be fined, only blocked.

Aside from that it opens the door for more regulation. SOPA/PIPA may not be full on censorship but this kicks that door open legally speaking. The argument to make it ok for the government to monitor what you say online and arrest you for it is palpable.
I agree this won't kill piracy at all, its likely to aid it from my understanding. The thing about SOPA and PIPA is I don't even care about the piracy stuff, because the bill are written as such that they don't affect it. The muck up other things, like the existance of LG. All the times we've had trouble with Gaia in the past, particuarly the last time, in a SOPA world Aleena and Arti go to jail, LG goes down, people that posted accounts go to jail, our host gets fine, ect. Its not pretty.(Clover you get this but I like examples and I like making people aware.)
