Joe - this probably isn't the right forum for the discussion and 9 times out of 10 I am on your side of this discussion because most of what you have said is correct. However, a change in the Supreme Court's make-up will indeed allow for new interpretations of what the Second Amendment protects and does not protect. And while you are mostly correct in saying that future courts will be bound by the precedents that you cite, the fact is that there is no realistic appeal of a Supreme Court decision, so a future Court dominated by Liberal appointees may well circumvent
Heller,
McDonald and other cases that you reference. Don't forget that in these cases, the Court appeared to have broken with previous precedent (
Miller v. Texas, 153 U.S. 535 (1894)
http://www.constitution.org/2ll/bardwell/miller_v_texas.txt ) in which the Court appeared to suggest that the Second Amendment did not apply to the States/State Law, or
http://www.constitution.org/2ll/bardwell/presser.txt Presser vs Illinois (1896) in which the Court seemingly overturned earlier precedent regarding the relationship of the Second Amendment to those in a "militia".
The point being, let us not forget another populist demagogue President, Andrew Jackson, and his response to the Court's ruling in
Worcester v. Georgia, 31 U.S. (6 Pet.) 515 (1832). Of the decision, Jackson said "
Mr Marshall [Chief Justice] has made his decision, now let him enforce it". The Court was unable to do so.
So, don't rely on the Court or the sanctity of the law. If the Left is able to make gun ownership less socially acceptable, and that is their agenda with terms like "assault weapon", "high capacity assault magazines" and "weapons of war", they can run whatever they want through Congress and you will obey or go to jail. There may or may not be a Court ruling later and it may or may not matter.
I have no interest in these EBRs, ARs or AKs, and find them a little puerile and a lot stupid, but I will defend with my utmost the legitimate right of my fellow citizen to keep and bear stupid and puerile arms that he may defend me when the Left comes after my much more refined and mature arms.
