> Gun ownership is baked into our founding documentation (The Constitution); as such, it's part of the very premise of our governmental foundation.
The irony here is that this court strikes down a clause of the Gun Control Act 1968 on the grounds that it is "not consistent with the United States' 'historical tradition of firearm regulation'" – and yet the very Supreme Court precedents it is applying in doing so are themselves not consistent with that tradition.
The 2nd Amendment was only intended to be a limit on federal gun laws; its authors didn't intend it to apply to the states, and nobody at the time understood it as doing so. Whether and to what extent state and local governments could regulate gun ownership was seen as a matter for state constitutions and state courts, not something the federal government (in any of its three branches) should get involved in.
Then the 14th Amendment was enacted, to try to prevent the defeated Confederate states from oppressing the newly freed slaves. Nobody at the time thought it had any relevance to non-discriminatory gun laws. I think its framers would have supported its use to overturn racially discriminatory state or local gun laws, but they would have seen racially neutral gun regulation as outside its intended scope.
The idea that non-discriminatory state and local (as opposed to federal) gun laws can violate the combination of the 2nd and 14th Amendments was introduced by the Supreme Court in 2010 (McDonald v Chicago). There is no evidence that the original authors of either Amendment would have foresaw or expected that outcome, and so was a major deviation from the "the United States' 'historical tradition of firearm regulation'".
The Gun Control Act 1968 is of course a federal law, so overturning it is not prima facie inconsistent with the original meaning of the 2nd Amendment. However, the logic of the decision (and the precedents it is based on) apply equally to equivalent state and local gun laws and regulations, which is a radical deviation from the original intentions behind the 2nd and 14th Amendments.
