From a sufficiently conservative point of view, SOPA outlaws piracy. Of course they're not interested in the pirates explaining technical details of pirating. They know it when they see it.
From a sufficiently lucrative point of view, SOPA outlaws potential businesses. Of course, they're not interested in the entrepreneurs explaining technical details of more businesses. They know it when they see it.
From a point where you take bribes (don't call it lobbying) from companies that would profit from SOPA and consequently vote for something you have no idea what it is, it's immoral and should get your ass fired!
