Another interesting quote, but I'd be far more interested in concrete examples. The biggest problem is restrictions on the freedom to dissent. I agree that is a big problem (if not the central problem) with regard to government surveillance. Beyond that, though, there are some laws that should be changed (controversial issues like gay marriage, etc.), but what else? What am I wrongfully denied the freedom to do?

I hope you realize that "you don't know how enslaved you are" is really a terrible catchphrase for a movement. People just roll their eyes when they hear that. You need to back it up with something they can relate to.
