I find it hard to believe the the 2nd Amendment is exclusively for national defense

[jimmy the one]

39. my friends & countrymen

hans: You cited Sam Adams, though leaving off the relevant portion which indicated exactly who Coxe was responding to.

ABRACADABRA! Hiding in PLAIN SIGHT, hans sinks like a lead balloon: The power of the sword, say the minority of Pennsylvania, is in the hands of Congress. My friends and countrymen , it is not so, for the powers of the sword are in the hands of the yeomanry of America from 16 to 60. The militia of these free commonwealths, entitled and accustomed to their arms, when compared with any possible army, must be tremendous and irresistible. Who are the militia? Are they not ourselves? .. Congress has no power to disarm the militia.

Now do you see what I meant all along, hans? Who pray tell, was Tench Coxe addressing in his speech/writing, using Sam Adams 2ndA draft as a basis? My {His} friends and countrymen, that's who Coxe was addressing, plain as day, how'd you miss it thou who readest so well? So I didn't 'leave off' to whom Coxe was addressing, did I?
.. This is what generally happens to charlatans, they get exposed sooner or later as their spindoctoring becomes more untenable & apparent.

hans: And you did contend that he was addressing Sam Adam's writing of two weeks prior: "Note that in the first draft of 2ndA above, there is no mention of a militia - sam adams simply said congress could not 'prevent the people of the United States, who are peaceable citizens, from keeping their own arms'. In response to this proposed amendment/draft, tench coxe wrote 2 wks later feb20,1788"

.. more of hans delusionary spindoctoring; Coxe was not addressing Sam Adams personally, he was referencing his 2ndA draft. Most readers will understand that 'in response to (Sam Adams) proposed amendment' coxe was alluding to it, & addressed his concerns to his 'friends & countrymen'.

hans: So sober up, take a long nap, or do whatever it is you need to do to bring yourself back to reality.

I'd say the same to you now that you've been exposed again, but I doubt it would help.
Worth a try, tho.
