Most Americans would agree. US gun culture has it's problems. But to ignore the extent to which the mainstream gun control movement is largely a political scapegoat for the cyclical violence enabled by the war on drugs also misses the point...because making the communities most impacted by gun violence safer is supposedly the point of our gun control movement. So in it's political context, the current US gun control campaign has been led by a reductionist viewpoint as well. And since fewer Americans have exposure to guns nowadays besides movies/video games, it's that much easier to misinform them and label any gun control skeptic as some NRA shill.
If US gun violence was a priority merely on the basis of its severity next to the rest of the developed world, then we would be combating a host of other public health issues/crisis that take way more American lives each year. There's obesity/heart disease, drug addiction, depression, cancer,......the list goes on really. Gun violence is just a sexier issue for politicians to engage.
