Well, only if they are fools who don't study history.
When "military grade weaponry" isn't available, insurgents steal it from the military, adapt weapons that are available to their own use, or manufacture weapons as needed. Clearly "gun control" is no threat to an insurgency.
Gun control is no threat to the assassin.
Gun control is no threat to the criminal.
Gun control is only a threat to someone who has something to lose by not playing by the rules.
In America, or what used to be America, the right of the people to keep and bear arms has been a hotly debated topic for centuries. In the Dred Scott case the Supreme Court ruled that negroes could not go free as then they would enjoy the same rights as whites, including the ability to keep and bear arms where ever they chose. The thought of armed, free, blacks (or in the case of New York, immigrants) was so scary that white people willingly laid their own legal traps against gun ownership.
The idea behind "gun control" has always been that the "uncivilized" should be mastered by their betters. Always.
No matter the language they hide it in, "for the children", gun control has always been about keeping those uppity niggers in their place as "a reasonable solution."
When a politician talks about "second amendment remedies" liberals are reduced to pants shitting hysterics. When private citizens talk about second amendment remedies, the liberals like to use that as yet another excuse that "the uncivilized niggers" need to be disarmed so that the good liberal (white) folk can rest easy from the threat of those who would be free. Joan Peterson, you are a racist small minded and petty person with delusions of both adequacy and relevance.
The second amendment has always been our "Sword of Damocles" that has hung over politics in this nation. When the South withdrew consent by force of arms, it took force of arms and an invasion to push a political agenda down the throats of those who didn't want it. After Waco and Ruby Ridge who thinks that it "can't happen here, again?"
"Some are whigs, liberals, democrats, call them what you please. Others are tories, serviles, aristocrats, &c. The latter fear the people, and wish to transfer all power to the higher classes of society; the former consider the people as the safest depository of power in the last resort; they cherish them therefore, and wish to leave in them all the powers to the exercise of which they are competent." Thomas JeffersonWhat good old TJ was trying to tell us, is that those who would be your masters want the power only for themselves. And TJ would be ashamed of how the term "democrat" has been twisted into what he considered "aristocrat." The 2nd Amendment is all about keeping an armed an dangerous populace. Armed with weapons of war, what the liberals call "military grade weapons" is the intent of the 2nd. Hence the "militia" language. If the arms are not suitable for use in the militia they wouldn't need protecting. The Founding Fathers knew this. What they underestimated was the stupidity of the men that followed.
But what does that matter? I can make nitric acid from urine over time (anyone can, just need access to your own urine and some readily available reagents). Once you have nitric acid all sorts of neat explosives are readily synthesized. So what if it is illegal? If you are going to break a few laws, might as well make them BIG ones, right? So what if making guns illegal has never stopped an insurgency, EVER. Clearly gun control has nothing to do with political stability.
Gun control is the worst kind of nostrum, like opium it makes people feel a little better while slowly killing them as they have to take more and more of it to feed a mindless, irrational addiction. There is one good medical use for opium, palliative care, when a terminal patient just needs to be made comfortable before death. Gun control...less useful than opium.
The problem with disarming a populace to gain political power is that you make rebellion ever more likely. And once the people are "fully disarmed" and you are able to implement your "final solution" to build your utopia, well that is the time for one of those unpossible insurgencies to happen.
