Rand Paul is a bad man who refuses to learn from other people, and is only interested in hearing himself talk.
Rand Paul hates all aspects of American foreign policy including our NSA. He denies the Islamic threat and says our wars are just for "the chosen people" (even though they benefit the whole world, because the Muslims want world domination/the Caliphate).
The NSA is not out to hurt American citizens. The NSA intercepts over a billion emails, phone calls, texts, etc. worldwide to find out information on terrorism that could save American lives.
