SOPA Act

This. They should make the bill title clear enough that people who don't read it know what the bill is doing in the broad spectrum.
Obviously PIPA isnt just stepping in to child pornography. It's doing a lot more, and that should be made more clear.
No idea how they would do that though.

It's a deliberate choice. Politics is a lot about how you're able to market yourself towards a public. These laws are the same. If the title is catchy and well meaning, it gets support. People don't read those bills, they get someone else to read and summarize it for them. Only the REALLY good politicians are able to read for themselves.
