I mean, I simply disagree. Violence is always a failure, either of policy, or of personal behavior. Enabling people to escalate that failure to a deadly one with the twitch of a finger is simply not an acceptable paradigm. An armed society, contrary to the witticism, will never be a polite society, because it makes it stupendously easy for bad actors to cause disproportionate harm, relative to the ability of the community to reasonably prepare for. Removing guns entirely is the only reasonable solution if you actually want a free and peaceful society.
