The Second Amendment certainly didn't give blacks the right to own guns. That took the 14th Amendment. And even so, gun control to keep blacks and others from owning firearms was still pervasive.
Pre-14th amendment "Rights" were only protected from Federal interference. States could thus restrict them any way they wished. I'm sure there is another clause in the constitution that really should have forbidden gun control being used exclusively against blacks but they just ignored it. Its not the second amendment though. At the time period, gun control at a state level was legal.
The 14th changed that. Now gun control anywhere is unconstitutional.
And yeah "Arms" wouldn't really include nukes. The reason it includes machine guns is because of this: Liberals say "The weaponry available now is different than back then."
True.
But the military also has better weapons now, and the whole idea was so that the common citizenry would be served by the government, rather than serving it. It was like the final, ultimate check and balance.
I don't know if canons (More equivalent to modern artilery than nukes) would have been included, but since they aren't carried as an "Arm" I don't see why they necessarily should be. Not that I'd have too much of a problem with someone that DIDN'T have a criminal record from having one
Nukes are different than anything else on the planet. We don't want some COUNTRIES having nukes. The idea of letting an individual own them is even farther than even I am going to theorize.
That said, I'd trust a US state government with one (Any of them) before I'd trust Iran.
Where I sometimes debate with myself is whether or not "Arms" that contain explosives are really arms. I'd see that as much more legitimately debatable. Machine guns are functionally no different than semi-automatic guns, they can sometimes even be the same gun and bullets! They just shoot faster.
