There may be an Internet black-out tomorrow (among certain sites) in protest of two controversial pieces of federal legislation: SOPA (Stop Online Piracy Act, or HR3261) in the House of Representatives, and PIPA (S968) in the Senate. There is fear that these pieces of legislation, if enacted, could threaten freedom of speech on the Internet. To learn about the case against SOPA and PIPA, see Craigslist’s article, and also the article and short video by WordPress.
Liberals and conservatives are on both sides of this issue. As you can see here, Democrats Chuck Schumer and Diane Feinstein are on the same side (the “pro” side) as Republicans Lamar Alexander, Tom Coburn, and Ben Quayle. On the side that is against these bills, you have Nancy Pelosi, Michele Bachmann, and Rand and Ron Paul.
Fortunately, the bills may be revised (see here), and President Obama has pledged to oppose any bill that will threaten free speech. I may very well call my Senators and representative tomorrow, though, since there are powerful and wealthy interests that are supporting these bills.
