I just have to put this out there because it seems the hundreds or thousands of artistic protestors of SOPA are protesting the wrong thing! SOPA is NOT censorship. At least not in the way that it is being shown by artists. Commonly, an anti-sopa poster or drawing will show parts of the a person, a face, the earth, or even the internet being CENSORED. That isnt what SOPA does. Sopa is meant to protect against piracy, and is more specifically meant for taking down foreign websites that infringe on copyrights. Now this would be fine and dandy, but SOPA has such a general definition of aiding or conducting piracy that it leaves thousands upon thousands of regularly used sites in the crossfire.
This is not censorship, though, because copyright infringement IS a crime, so its not like they are filtering websites, they are punishing them by taking them down. This could be for something as simple as a link, or even something submitted on a portal by a random person. This would constitute the site being taken down. I would say this is a lot closer to secret police than censorship, and its far scarier. Unlike censorship, which is targeted, SOPA can affect any website, from Facebook and Twitter, to Newgrounds and even Stickpage. All it would take is for someone to post a copyright infringing material and the entire site could be gone without warning. Not even the owners themselves would know until its already too late.
SOPA isnt censorship, its FAR, FAR WORSE!
