We all learn in school that the judicial, legislative and executive branches of government must check and balance each other. But other non state institutions must participate in this important system of checks and balances as well. These checking institutions include the academy, the media, religious institutions and NGOs.
Should we have background checks, waiting periods? To drive a car you have to pass a test that shows you know how to drive your car safely, you should have to do the same thing with guns.
Non-crazy gun advocates - the ones who aren't stockpiling in preparation for a zombie invasion - don't like the idea of expanding background checks because they think it'll be a lot more paperwork. And it probably would make it more difficult to sell guns at, say, a flea market.
Religion forbids us from assuming a God-like character. This is especially true in politics and government, where limiting the power of the state, division of powers, and the doctrine of checks and balances are established in order to prevent accumulation of power that might lead to such Godly claims.
Ronald Reagan was long thought to be the most conservative of Republicans. And by any standard today he is the most popular Republican in modern history. Yet he raised taxes 11 times, supported a ban on assault rifles and the Brady Bill, which mandated background checks, and established amnesty for 3 million undocumented workers.
