They also mainly live is cities with police forces that are politically and financially motivated to have low response times. They aren't calling a sheriff that may be an hour away. For most of the world truth on only a matter of whose ox gets gored. How people see gun regulation depends for most on how they see guns, friend for self protection, sport, hobby etc., or evil with the risk of being because of what's on the news.
But understand, I support tightening gun restrictions designed to keep guns out of the hands of folk who may rationally represent a danger.
One of the key triggers that will make a man feel worthless is to be rejected by a woman, something self haters will unconsciously bring about because they can't believe in love and constantly test their partner's loyalty, driving them away in the process. Once this is triggered a self hater can become very dangerous. Same thing with losing a job or losing anything ego building related. This is all the more the case because the general population has no idea this is what is happening psychologically because everybody is avoiding that pain of being put down as children.
Without guns there would be no mass killings with guns but that's not where we are. No solution will be forthcoming from the crazies on both sides.
