Yeah, never make the mistake of believing that gun restrictions are about fighting crime, or enhancing "public safety" or any of that nonsense. Those are the selling points, the lies, the "spoonful of sugar" that makes the "medicine" of authoritarianism go down. The only purpose of gun restrictions, ever, has been to fight YOU; the law-abiding, liberty-loving American.
In the broader picture, it is a war against Judeo/Christian Civilization. De-emphasizing, and eventually eliminating, the protections of the American second amendment is just one little front in that war, but it's a pretty important one for authoritarians. They all hate it precisely because it puts the lie to their claims of authority, their ideal of Central Planning and so on. The second amendment, more than anything else, recognizes the fact that the true power (politically speaking) lies in the hands of the individual citizen, acting on his own for his and his family's and community's own benefit, buy his own discernment and judgment, guided by Judeo/Christian principles (essentially embodied in the Ten Commandments). NOTHING on Earth will piss off an authoritarian more than that ideal, and so they'll forget all their differences to go after you, and then, once they've taken care of you, they'll resume killing each other later.
