Seems as though you and herdman do not care. The conversation will continue whether either of you like it or not. It is not about the 2d amendment. It is about trying to keep our society safer. Car wrecks and obesity may well kill more people every year. These folks chose to drive a car and or over eat. We are usually aware of the risks involved with either. Victims of mass shootings did not choose to die and certainly were not aware of the risk of going to school, a movie, outdoor concert, or shopping. If this is the world you want, then you are in a minority. The 2d amendment is a right. With that also comes some serious responsibility. If this right is abused, i.e. mass shootings of innocent men, women and children, then, as a society, we need to develop plans that will minimize them. Identifying folks with addictions, anti social behavior, history of violent outbursts, sexual assaults, through the current law enforcement records would be a start. Treat them in the same way you treat an Addict in drug court. Keep yourself out of trouble, clean, involved in constructive activity and you will regain the right to own a firearm. If you don't, then you will not allowed to purchase a gun for the rest of your life. If only 30% of Americans own guns, then we are not talking about a big burden here.
We are talking about keeping weapons from folks that are not "Law Abiding", until they demonstrate some life changes. That would help them, and keep us safer. And I do not suggest this would eliminate all mass shootings. It would certainly be worth trying something. Not sure I understand your anger, 76. You don't expect to be able to dish out insults to folks without some kind of response.
