SOPA being waved around by the right hand is just a loud distraction from what the left hand is doing.
For you see the H.R.1981, Protecting Children From Internet Pornographers Act of 2011 is lying in wait. It is the ace up Lamar Smith’s sleeve.
Just copy and paste the contents of SOPA onto the end of PCIP, it will be passed without debate let alone opposition. No politician in the USA will oppose anti-child pornography legislation.
