I think the pro SOPA side won. I believe this because they refuted the against sides argument better. I felt like the against side based their argument heavily on the fact that SOPA is censorship and against free speech, but the pro side explained to us that it will only shut down foreign sights with pirated material, and it wasn't even shutting those sights down, it was just blocking the links on search engines. They basically said its not violating free speech, its protecting property. The con side did have a much more structured approach, but they didn't refute as well as the pro side, and because of this I'm going to have to go with the pro side.
