This is objectively false. You're attempting to portray a personal opinion as fact. Bad form, and definitely not appropriate for HN. Please don't do that here.
If nobody had guns, you wouldn't need to a gun to protect yourself from someone else with a gun.
The problem of course is that the genie is already out of the bottle. We can't take the guns away, they're all over the place in the USA already. Even if the Second Amendment was repealed, all that would happen is that only criminals would have guns.
We're fucked and there's no solution.
