First of all the actual quote is, "Congress have no power to disarm the militia. Their swords, and every other terrible implement of the soldier, are the birth-right of an American ..."
Second, the quote is from Tench Coxe, a friend of James Madison. Mr. Coxe was not a Founding Father.
And third, the quote was from 1788, years before the 2nd Amendment was enacted.
He was a delegate to a State Constitutional convention. His writings appeared in published journals.
Makes him a hell of a lot more of a founding father than some Judge deliberatively misinterpreting the plain text of the Constitution decades, even centuries later.
