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

25. miller was apolitical

N-uni: "The heller decision was split along political lines, 5-4." Irrelevant

I suppose it would be spun as being irrelevant to pro gun adherents; to those with a more in depth understanding of the issue, it's very relevant, since the decision hinged on one justice, kennedy. The nra actually didn't want to pursue heller, afraid they'd lose.

I wrote: {Miller} was a unanimous 8-0 ruling.. heller split along political lines, 5-4.
n-uni replied: The Dred Scott decision was 7 - 2; that's higher than 5 - 4, so what's your point?

You are feigning ignorance imo; Miller unanimously & apolitically rendered a militia interpretation of 2ndA in 1939, while heller 2008 was a political decision, pandering to a rightwing republican base & an assiduous & insidious gun lobby.

You also didn't reply to this concern I had: ".. the author you mention probably meant to say the 2ndA's purpose was not to guard against a tyrannical domestic, or perhaps foreign govt.. You might be conflating this concept with the bor amendments being restrictions on the govt (congress); do you think this the case?"

I wrote: ..the rationale for RKBA has collapsed into oblivion...
N-uni: Not according to your Tenche Coxe citation.

You're naivete is showing; of course the tench coxe citation in 1788 wouldn't show that the 2ndA has fallen into oblivion today. See if you can figure out why, with the clues I've given.

Nuclear Unicorn Semi-auto long rifles are not "military style assault weapons" except in appearance .. Actual military weapons are 3-round burst or full-auto.

Right out of nra songbook, a specious red herring; I wrote 'military style assault rifles', which includes bushmaster & AK47 & 74 & others, of course non automatic but still 'military style asslt rifles'. An m16 is a 'military assault rifle', to wit, in either 3-rd select fire or full auto.
What with such little recoil & bumpfire capability, an ar15 bushmaster can fire over 100 rds per minute, not near automatic fire of ~600/min of an m16, but limited more by the magazine size. You generally cannot do that with larger caliber semi-auto rifles.
