Who do you think is going to disdisarm willingly? Educated, well off middle-upper class, or those you describe? Why must the middle and upper classes sacrifice their safety when a substantial subset of the population violently dehumanizes them? Simply for having more, at that.

You're also imposing your cultural norms onto others. Guns and violence are simply a way of life for millions of people. Good luck taking those guns from your ivory tower.
