I LOVE throwing these various "red state demographics" of the .mil, the oath, election polls of .mil members for the past 30-odd years etc. as yet one more point when debating an anti who tries the "you can't fight the modern US .mil with tanks and planes/drones" gambit to imply the 2A is "outdated" with me.
It really gets them thinking and shuts them up at the same time.
However, privately, while all this anecdotal evidence heartens me, The Milgram experiment and the Stanford Prison Experiment gives me the dark feeling that we at least ought to cut any estimates of the .mil "on our side" in half, at least.
Given the right timing, and the right pressure, there's an Auschwitz prison guard in almost all of us somewhere.
Which of course makes the 2A all the more important.
