Okay, first of all MyChemicalRomance ROCKS and second, to make this short and simple, Yes. It does have something to do with online censoring. Basically, the government is going to shut down every website that has something to do with copyrighting. This is including Youtube and Facebook, probably even Google/Yahoo/Wikipedia. So, you better vote for NO. We need our freedom that we came to America for.
I'm not well acquainted with PIPA yet, but SOPA has been shot down and will not pass. What it was meant to do was to protect online piracy - people offering movies, TV shows, songs, etc., on their websites - by closing down the website to American visitors. All it would take is a complaint from someone who owns copyrighted material on that website for the American government to shut it down.
The problem arises in that the entire website is shut down and not just the page with the material. On top of that, even if a website offers a link to ANOTHER website that offers the materials can be shut down by the US Government.
What does this mean? It means that complaints can shut down YouTube, Twitter, Facebook, and any number of other websites which fall under the law. The US Government would literally rule the Internet and determine what can or cannot be there. It would be global censorship.
