Baldr, I question your goal, “My goal, and the goal of Gun Control in general, is to reduce gun violence…”
Had you said, “criminal violence” then I would be with you. But the way it is worded your goal could conceivably be completely achieved (zero injuries inflicted with a firearm) yet have a murder rate that is 100 times greater than what we have now.
That is why the “gun deaths” data you presented is of almost no interest to me. I didn’t dig into it to make certain but I suspect it includes “gun deaths” that were justifiable homicide by the police and private citizens protecting innocent life. It probably also includes suicides.
It is because of these issues there is Just One Question that needs to be answered before I can see any point in having a discussion about placing restrictions on the specific enumerated right to keep and bear arms. That question is: Can you demonstrate one time or place, throughout all history, where the average person was made safer by restricting access to handheld weapons? If you can’t successfully answer that question affirmatively then I don’t see any point in having a discussion.
