Sorry, but the "state militia" is NOT the National Guard. The National Guard is a part of the "organized militia" that is stationed in the states and which the Federal Government allows the state governments to exercise some usage of.
There are several states (I forget which ones) that currently maintain a state militia in addition to and apart from the National Guard. That other states currently do NOT maintain such does NOT abrogate their right to organize such at any time they so choose.
I have the phrase "state militia" in quotes because that's how His Royal Highness Reggie B. Walton (L-FJESL) would respond to both your arguments about the National Guard. I would bet a double sawbuck that Reggie the Ninny would actually tell you to your face that the "state militia" is the National Guard, and actually believe it.
It doesn't matter what we think about these issues on FR, even though we are correct. What matters is what the 800-odd members of the Federal Judicial Executive SuperLegislature think.
