SOPA is up for debate RIGHT NOW

I have to admit that I've been having a bit of trouble following the SOPA issue. I know what's going on, I've heard arguments, and I think I know enough to know I'm against it.  In keeping with that, I've written my representative. That said, I don't know enough about the situation to actually be able to convey what I know about it in an intelligible way.

Right now, I'm watching the live stream of the debate.  At the moment, a representative named Mr. Lungren (no idea where he's from) who's arguing that there's something about credit cards that's a really good idea.  I don't know exactly what.  I do know that the way they're talking about the issue seems to imply a worldview and political alignment fundamentally incompatible with mine.

Here's the website I'm getting the stream from, and I'd love to have a conversation about the bill with any readers who know more than a little about it in the comments.
