"Why do you need an AR15?"

[montana]

"While none of the Founders liked the idea of a standing army, the majority (Madison strongly included) believed it to be necessary. The Second Amendment was not a response to Anti-federalist criticism of the standing army. All the Bill of Rights were added because of a desire to disarm what Madison and the other Federalists saw as an Anti-federalist quibble, a strawman objection to the lack of a Bill of Rights which was intended to excite the fear and passion of the masses but which statesmen on both sides viewed as negligible. Madison just wrote up a set of principles ― of truisms ― in which everybody believed, and the Congress duly passed it as the Bill of Rights. Two of these truisms that got cobbled into one article were: that there is a natural right to be armed; and that militias are a good thing.
