Gun Control seems silly to me. Taking guns away from the concerned citizens leaves guns in the hands of the military, the police and the bad guys. I don't know how many guns are currently circulating. The issue seems to be dealing with mental health issues. I doubt there is much desire to try thinking about those issues. The Lady in Sandy Hook who owned the guns followed the law. They were not illegal guns. The confused son took the guns and killed his mother, and then proceeded to shoot up the school.
Yes, ipad apps simulating shotgun blasts for hunting, or whatever are probably inappropriate. All of the Call of Duty, and other first person shooting games might also be questionable, but I don't think that'll get addressed. Glorification of violence should also stop, but it probably won't.
We can decide to co-exist, but that requires accepting other people. Too many are not accepting.
There should be a better way forward, however when a person is surrounded inside of an echo chamber outside opinions don't survive very long.
