When the constitution was ratified, the militia was the only defense that the United States had, and all able bodied men were expected to be ready to serve.
First off, the Constitutional Army was created by the Revolutionary Congress to be an OFFENSIVE force against the British Army who they were in TREASONOUS REBELLION against.
Secondly, the Constitutional Army was a Government run Military, supplemented by local militias but in itself, not a people's militia
Thirdly, the 2nd Amendment of the Constitution was passed in 1791, well after the Revolutionary War and has nothing to do with the Constitutional Army or the offensive actions taken against the British.
Fourthly, the 2nd Amendment states "... being necessary to the security of a free State, the right of the people to keep and bear Arms" implies that this right was granted to the people to SECURE THEIR FREEDOM. Part of the security of freedom is to be secure against the tyranny of their own government.
And finally, if your stance was adopted, we must logically make all Law Enforcement and Gun Carrying Services Militias against an unarmed civil population, turning us into a MARTIAL POLICE STATE in every sense of the word.
So yeah -- you have a very unpopular opinion and I hope to god we the people get to rise our guns against people like you, in order to preserve or freedoms if you try to pull that shit.
