I have a question. Are you a registered voter? I mean, do you vote? Because you're a perfect example of why we need to change the Constitution to require passing a test on the Constitution and intelligence before allowing a person to vote.
What you are suggesting is that the Supreme Court gets to actually change the Constitution, by changing the meaning of the words, at their will, without considering Article V. If today, they say a thing is unconstitutional and tomorrow they say otherwise, you're suggesting that it is the Constitution that changed, that their word is as good as a constitutional amendment. And, hypocritically, you're saying that on a computer that didn't exist 200+ years ago, exercising your right to free speech.
If Congress believes gun laws need to be updated from what they were 200 years ago, or if the legislatures of two-thirds of the states believe it, then pass an amendment to the Constitution. Congress doesn't get to change the Constitution just because they want to reserve public safety and security. In fact, you won't find preserving public safety and security in the enumerated powers of Congress.
The Congress shall have Power To lay and collect Taxes, Duties, Imposts and Excises, to pay the Debts and provide for the common Defense and general Welfare of the United States; but all Duties, Imposts and Excises shall be uniform throughout the United States;
To borrow on the credit of the United States;
To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes;
To establish a uniform Rule of Naturalization, and uniform Laws on the subject of Bankruptcies throughout the United States;
To coin Money, regulate the Value thereof, and of foreign Coin, and fix the Standard of Weights and Measures;
To provide for the Punishment of counterfeiting the Securities and current Coin of the United States;
To establish Post Offices and Post Roads;
To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries;
To constitute Tribunals inferior to the supreme Court;
To define and punish Piracies and Felonies committed on the high Seas, and Offenses against the Law of Nations;
To declare War, grant Letters of Marque and Reprisal, and make Rules concerning Captures on Land and Water;
To raise and support Armies, but no Appropriation of Money to that Use shall be for a longer Term than two Years;
To provide and maintain a Navy;
To make Rules for the Government and Regulation of the land and naval Forces;
To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions;
To provide for organizing, arming, and disciplining, the Militia, and for governing such Part of them as may be employed in the Service of the United States, reserving to the States respectively, the Appointment of the Officers, and the Authority of training the Militia according to the discipline prescribed by Congress;
To exercise exclusive Legislation in all Cases whatsoever, over such District (not exceeding ten Miles square) as may, by Cession of particular States, and the acceptance of Congress, become the Seat of the Government of the United States, and to exercise like Authority over all Places purchased by the Consent of the Legislature of the State in which the Same shall be, for the Erection of Forts, Magazines, Arsenals, dock-Yards, and other needful Buildings; And
To make all Laws which shall be necessary and proper for carrying into Execution the foregoing Powers, and all other Powers vested by this Constitution in the Government of the United States, or in any Department or Officer thereof.
And, no, the current gun control laws are not the law of the land. Oh, sure, at the point of a gun the government will force compliance but that doesn't mean the laws are legal. The Supremacy Clause explicitly states that the Constitution and only those laws created following the Constitution are the supreme law of the land.
This Constitution, and the laws of the United States which shall be made in pursuance thereof; and all treaties made, or which shall be made, under the authority of the United States, shall be the supreme law of the land; and the judges in every state shall be bound thereby, anything in the Constitution or laws of any State to the contrary notwithstanding.
Laws that do not follow the Constitution are as if they have never existed. From American Jurisprudence 2d:
§ 195 Generally
The general rule is that an unconstitutional statute, whether federal or state, though having the form and name of law, is in reality no law(1) but is wholly void(2) and ineffective for any purpose.(3) Since unconstitutionality dates from the time of its enactment and not merely from the date of the decision so branding it,(4) an unconstitutional law, in legal contemplation, is as inoperative as if it had never been passed(5) and never existed;(6) that is, it is void ab initio.(7) Such a statute leaves the question that it purports to settle just as it would be had the statute not been enacted.(8)
Since an unconstitutional law is void, it follows that generally the statute imposes no duties,(9) confers no rights,(10) creates no office(11) or liabilities,(12) bestows no power or authority on anyone,(13) affords no protection,(14) is incapable of creating any rights or obligations,(15) does not allow for the granting of any relief,(16) and justifies no acts performed under it.(17)
Again, by force of their arms, the government is able to force compliance but it is by tyranny that they do so and that is exactly why the 2nd Amendment was created, as a defense against such tyranny.
