"Clayton Cramer certainly is a professional historian -- and one, I might add, who has taken down a far more prominent professor, Michael Belesiles, by checking his work and showing it was falsified."
No, he is not. That take down of Belesiles was conducted while Cramer was a hack asking the NRA for money to discredit Belesiles, not an academic. Calling him a professional historian because he caught some fraudulent work while a grad student and worked as a software engineer is absurd. I do enjoy how the NRA and their acolytes make a lot of hay about Belesiles but still cite with great frequency Lott's fraudulent work on guns. Their standards are breathtakingly consistent. Of course, Lott wasn't swiftboated out of academia like Belesiles. So much for the liberal bias of the ivory tower.
"Well, I suppose it could, except, as pointed out in the brief, Pennsylvania's Indian situation was highly unique "
What? PA's Indian situation was unique? Where does it say that PA was the only state subject to Indian attacks? It says nothing of the sort. Only that PA did not have a militia because of its Quaker orientation and frontiersmen petitioned the colonial government to organize one. Why couldn't Vermont, whose militia similarly did not exist after the revolutionary war and was not a state, as the Green Mountain Boys had been disbanded, face similar issues? In fact Royalton, Vermont had been burnt down by Indians in 1780, and Vermont was having trouble with New York and thus wasn't recognized as a state by the Continental Congress. You're playing gotcha with the PA point where there is no there there.
"I love it how you put quotation marks around words I didn't use. What I said was, "15 is hardly that impressive." And it's not."
So you're quibbling over whether unimpressive means the same thing as not that impressive, and then you proceed to call the brief unimpressive anyway. This is why it's so tedious to discuss anything with you.
"They threw words at an obviously fatal problem"
What fatal problem? You and Scalia are clinging to extremely rare and idiosyncratic uses of phrases, phrases that propped up in minority proposals that failed to gain popular support, and claiming that they were commonly used in such ways.
"but I see you're just going to keep making arguments to authority"
No I'm referring to documents which you dismissed out of hand because you didn't read them. The only thing you bothered to read was Scalia's brief, because it confirmed your predetermined conclusion on the matter, even if Scalia is misusing the historical evidence for his claims (as he does with the Jacobite discussion).
You mention Footnote 10, all but one of Scalia's examples (of which there are 6 or 7, "plentiful") comes from 18th century UK. Only one from the United States. And Scalia later concedes that the phrase is used most commonly in a military sense, but is making the claim that it's not limited to that sense. Keep squeezing blood from turnips.
