We already have the war on drugs. SOPA is the first step to outlaw independent media. Indy media will be ok, as long as it never uses any kind of copyrighted content. The instant it does, Indy media gets gets shutdown by financial sanctions, and gets shut off the web.

Sure, it's not the end of the world. But try making a news site without using "clips from the news"
Try making a comedy site without having a George carlin or Jon Stewart clip.
Try making a music site without having a sample of commerical music. (or a copyrighted melody, or copyrighted lyrics)

People on the internet are free to remix culture, to reinvent it. Until SOPA passes we are free.
