You’re sincerely confused? It’s clear you have no background in anything military or perhaps even psychology. It’s power-projection. You’ve become so conditioned to believe that power-projection is only used as a tool of oppression that you’re overlooking the fact that it’s better to point guns than it is to face guns, and it’s certainly worse to face guns without one to point back. Would you rather cede power to those who desire it than support empowering those who would wield it to protect your right to exists? You want to exist in an ideal world? Be willing to fight for it – the ones who wish to oppress others are certainly willing to use violence to achieve their means. Once you’ve claimed victory over violent oppression, then you can set the guns aside and build a society around the flimsy concept of a disarmed society. Guns are still tools and have uses outside of violence, but that’s outside the scope of the point I’m making.
