Internet Blacklisting; yes or no?

For those of you who have not heard, there is currently a new bill before congress—S.3804—which proposes what I consider a rather terrifying proposition. According to demandprogress.org, this bill would allow the Attorney General and judicial system to create a internet blacklist comprised of sites they believed should be banned from the American public.

While I’m all for a little bit more security on the internet, it looks like this bill is taking it way too far. In all honesty, I don’t see how it’s that much different from what Mao is doing in China. But what’s your opinion? Are you for or against S.3804?
