The fact is, the US has a high level of gun-related violence. It's not about what happens in other countries when they change laws, it's about relative comparisons between similar countries and the US.
I believe it's your right to own a gun, and that right not be subject to any restriction upon your ownership or purchase. But the fact that needs to be faced is that the US has a high number of shootings that are a direct result of easy access to guns.
You can argue that if you have guns, you have shootings. You could argue it the same way as if you have free speech, you have a lot of inflammatory statements that cause contention and outrage. Freedom is messy.
What I'd like to see is advocates of gun ownership rights admit that gun-related violence is the consequence of such rights. Stop hedging. Use the "freedom is messy" argument and stand by it. Don't pretend that gun-related violence is not a direct consequence of easy access to guns.
Those who say that gun violence in Texas is lower than in New York are missing the point as they don't compare jurisdictions where gun ownership is severely restricted *outside* the US. Texas is a war zone compared with such places. Gun control therefore works. But that's like saying restricting freedom of speech results in less published disagreement. And it does.
And then we can ask, openly and honestly, why some people, some areas, some condtions, lead to high levels of gun-related violence.
