While correctly noting the role of personal responsibility, one must recognize that not everyone will not exercise it. It reminds me of the following:
“If men were angels, no government would be necessary. If angels were to govern men, neither external nor internal controls on government would be necessary. In framing a government which is to be administered by men over men, the great difficulty lies in this: you must first enable the government to control the governed; and in the next place oblige it to control itself. A dependence on the people is, no doubt, the primary control on the government; but experience has taught mankind the necessity of auxiliary precautions.”
― James Madison, The Federalist Papers
I'm a gun owner, but one who loathes the NRA and can't stand the disingenuous and sophomoric pretenses so many gun owners forward for owning their guns. It is enough for me to say "I like guns and target shooting." I don't uneed to wrap myself up in misconstrued and incomplete understandings of the Constitution or the 2nd Amendment. I also don't need to somehow pretend that my ownership is what keeps 'Merica free; or worse, I am somehow more patriotic for it. You know what sucks the fun out of a day at the gun range for me? Creepy gun nuts who wandered off the compound. Ugh.
