The best discussion of SOPA & PIPA I've found are on Wikipedia: Stop Online Piracy Act and PROTECT IP Act . Take a read and see what you think. (Nominally, Wikipedia is going dark today in protest of the bills, but I was able to get to these articles.)
Then, if you live in the US and want to join in asking Congress to vote "NO" on Internet censorship, follow this link to Google and add your name to the petition there: https://www.google.com/landing/takeaction/. Time is of the essence -- voting on these bills starts Jan. 24 -- so don't delay in informing yourself!
