That a well regulated militia, composed of the body of the people, trained to arms, is the proper, natural, and safe defence of a free state; that standing armies, in time of peace, should be avoided, as dangerous to liberty; and that, in all cases, the military should be under strict subordination to, and governed by, the civil power.
The founding fathers were very clear that standing armies are a threat to liberty. The writers of the Constitution wanted a decentralized militia of armed civilians, because it protects the country from both external and internal threats. If everyone is armed, tyranny by any one individual or group is impossible.
Obama is attempting to do the exact opposite. He wants to disarm all civilians and give himself absolute power. It is beyond mind-boggling that he is getting away with this.
