Your postings in this "One more Discharge" thread are as a vacuous as those points you assign to the "gun culture". You said your purpose was to shine a light on irresponsibility. Well yeah. But irresponsibility is a fortiori a cultural outlier. It isn't part of the gun culture.
I give you one point though, the gun culture stands in the way of meaningful policy responses to this problem. But the gun culture is not alone. The gun control culture is the same. I listened to a Kamala Harris speech this morning. She said in the America she wants, youngsters won't have to go to school in fear because she will ban assault weapons and impose universal background checks. Well, those measures wouldn't have stopped many of the mass shootings. In some instances where we have control measures in place, (Southern Springs Church) armed guards present, (Parkland) or ample warning signs from the mass murderer, (Fort Hood) for one reason or another, those measures failed.
There is, however, a measure that makes sense and has proven effective in other contexts. We need to increase the economic risks on those who manufacture and sell weapons. As I've said a gazzilion times, we need to repeal the immunity laws. I've heard two gun control advocates speak about this. Hillary Clinton who was typically dishonest about her description of the issue. And Jason Crow, a rookie Democrat from Colorado. Crow was so inept that the talk show host who interviewed him made Crow look like a dumbass on the immunity point. Repeal won't happen overnight. But it won't happen at all if we don't seek it. Had the administration and other gun control advocates started this discussion after Sandy Hook, (as I suggested here) we might be where we need to be now. The gun control advocates can't get past the reactionary response that we need more laws and regulations to fix this, not one fewer law. More law is in their DNA.
And does the lack of civil immunity work? Yes. Ask the opioid dispensing industry. The prescriptions are declining at a pretty good clip. But the void is being filled by easily produced fentanyl which is pouring across our border from Mexican and South American producers. But that is another problem.
