Here is an excerpt from that linked page:
"...Throughout history, legal theorists have split on whether the Second Amendment protects the rights of individuals to own guns or only the right to establish armed militias. But now some liberals are unexpectedly supporting the view that individuals have a constitutional right to own and use guns, and that gun control laws may be unconstitutional..."(Emphasis mine)
It has not been "throughout history" that the militia-only scam has been attempted. It is comparatively recent. I've heard Miller cited by later scam-artists. And I've heard reference to the last 40 years or so.
Watch that unexpected support from liberals.Scholarship proving the individual-rights theoryhas shot full of holes the militia-only theory, leaving thedoor open tocriticism that the 2nd Amendment is out-dated, unnecessary, etc.
