Edit:
Obviously, China has a constitution, but the freedoms enumerated there are not the same as those in America's. And those that are enumerated are pointless (like North Korea's constitution).
My point is that there's an inherent hypocrisy in saying we're more free than them, but then doing a tit-for-tat retaliatory measure. How can we be more free when we're doing the same things the other side is?
