This picture is circulating the Facebooks, I snagged it from "The Pragmatic Progressive Page".
It is absolutely, one hundred percent wooly headed leftie-libby insanity.
The 2nd Amendment to the US Constitution reads:
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.
There is absolutely no doubt that the people that wrote and approved this sucker were absolutely steeped in recent historical events. Historical events that were made up of an effort to free, by armed conflict, one part of a nation State from the rest of it. To take up arms against, they felt, a tyrannical controlling central governmental authority. To throw off the chains that bound them to that authority and to form a new Nation State.
During that conflict, the military might of the controlling central authority was deployed against citizens, including by trying to control their access to the very "arms" that might be used to resist said controlling central authority.
It is inexplicable to me how anyone with even a modicum of sense can view the 2nd Amendment as anything other than guaranteeing the ability of a local, semi-organized subset of a nation State to fight, with equivalent arms, against the military power of said national authority.
Consequently, the 2nd Amendment guarantees the right not just to muskets but to all of the arms available to the nation State itself.
Thus, Stinger missiles, F16s and M1 tanks are covered just as cedrtainly as your thirtyoughtsix deer rifle. The 100 round drum clip for an AR-15 style "rifle" as assuredly as hand-polished birdshot for Cheney's lovingly waxed Italian sparrow murderer.
