I can walk into a gun store in my town and buy military-grade weapons. You'd be shocked by the amount of firepower you can buy - 50 caliber sniper rifles and the same shotguns the Marines carry in Iraq or Afghanistan. It doesn't matter whether I know how to use these things - I can just walk into a store and buy them.
My personal feelings on marriage? Samuel Johnson once said that second marriages - although I could probably say this about any marriage - are about the triumph of hope over experience. I think that's true. I don't know that human beings were meant to mate for life or be monogamous. But, for me, the aspect of marriage that is troubling is that it's a contract that is governed by the state, and I don't want the state to have control over my personal affairs.
