How to think about violence

What counts as violence? Certainly a mass shooting, but how about being bumped on the subway? How do we balance our sensitivities with the brutal facts about the world? Can we regulate away everything that offends us? Is it really possible to live in a safe world? I think not. And I wonder what the point even is to the whole gun control debate. The real issue to be dealing with, in my opinion, is mental health care and support. I'd rather work towards a more compassionate system for derranged people than to pretend than anything substantive can be done about gun culture (which, by and large, is harmless).
