Wow! I feel a real kinship with you now. This is what it feels like to be stupid.
But now for those other points.
You rather missed my point about gun controls being a bad thing. Essentially you thought wrong. My point was a little more nuanced so I see how you may have missed it entirely. The whole gun control thing is a crock of shit and the reason is that on a practical level it would not work and it only services to make those virtue signaling this outrage and such feel a warm glow of smug righteous indignation that only the morally superior feel and the virtuous.
If they enact gun controls at a governmental level there will be pushback and it will go to the Supreme Court where Constitutionalists and Republican majority will overturn it. That is IF it actually gets to that stage and you know it won't.
If they make the states responsible for it, it will be enacted in places like Washington, California, New York, Illinois and the collective small Northern states on the Eastern seaboard. Most of the rest will be happy to keep the guns and the bad element will illegally purchase the guns and bring them into the states where they are limited.
People are likely to get all "out of my cold dead hands around it" and any time the government may seek to limit their rights they will consider it an attack on the Constitution by a tyranical government.
Even as a theory or imagine if, it is rather far-fetched and simply like saying "If we all were nice and treated each other with decency, there would be no murder and theft. We would be a Utopia." Same kind of bullshit. All it is saying is, I am virtuous and morally better and placing myself above others to make myself seem awesome. I am pretty "whatever" about your efforts
People in America would not respect the gun control limits you are suggesting. It will not happen.
decades of uncontrolled gun ownership has caused this?
You DID say that right? So Americans are allowed to own automatic rifles right? Yes or no? If YES is the answer then you are not in a position where you can actually converse about this as you are not well informed. If NO is the answer, then you will have to cede this point as dishonest or incorrect and we will get to another point of contention.
Will gun controls will reduce violence? Better ask the citizens of Chicago 600+ deaths this year in an area where there is gun control laws AND taking into effect for reasons I have already suggest it is virtually impossible to get nation-wide gun control laws , we will imagine a state like (I dunno) Virginia gets strict gun controls. What happens then? Does the gun violence rate go up or down? Where do the guns that people have that are limited go? Where do people in that state wanting to use controlled guns go? What really changes in the statistics and why do you imagine it may? What statistics have you to back this hypothetical?
