If they are just trying to shut down pirating sites, it would pass no problem, but they are trying to censor the entire internet. Say this passes and you make a RC video that has a copyrighted song in it, you are instantly a criminal. It goes wayyyy to far with the censoring.
With that said, I doubt it will pass. Too many are against it. This video makes some VERY good points...
