American Censorship Day

I have been seeing on many websites stating that congress wants to pass a bill on censoring websites like Facebook, Twitter, and for those who still use Myspace. What I mean by this is if a person posts on Facebook them singing a song they can be fined or even put in jail (not because of copyright!). Because of this law they can stop you from posting freely online. Does this sound like a violation of some constitutional rights? Yes put that's what they are going to ask to do. So if you have any of those social networking sites I say you send a letter to congress.
