Madison, who wrote the 2nd amendment went on to describe how the militia was a civilian militia with leaders of their own choosing and not to be controlled by the government or regular army. he also went on to describe what he saw the capabilities of the civilian militia were and how they could defeat the regular army if the government ever took arms against the people. of course the government trying to gain supreme power over the people would try to disarm the public. pin head liberal gun grabbers are too stupid to see this and attempt to aid them in their cause to make people submissive to the government.
That was back in the 1700's, when the "militia" and military both carried basically the same weapons: Muskets. And back when common citizens hunted and farmed and had to live rugged lives to survive, so really, aside from learning to march and salute, there wasn't a huge difference in "militia" and military.
TODAY?
The military is full of outstanding athletes, with world class weaponry, full time training, technology that 1980's movies could only dream of, tanks, drones, warships, etc, etc.
And the "militia" of right wing rednecks? Made up of 300 pound fatties on roto-scooters roving around Wal-Mart buying pork rinds, drinking Pabst Blue Ribbon on the recliner watching NASCAR, armed with an AR15 they bought with their tax return but have never been formally trained with?
YEAH.....I don't think the militia would win that one. Hell, there are 1,000,000 cops in America. I doubt "militia" could defeat them, much less the 3,000,000 man military.
