Setting aside the fact that gun violence in the US is largely the product of a fascist gun culture and decades of a simmering fascist insurgency, rather than guns qua guns…
…there’s a difference between a preference for less gun violence (understandable) and responding to fascist state murders by decrying people who want to defend themselves as “part of the problem” (obscene).
People do not cause gun violence merely by possessing a gun, as if committing some spooky action at a difference, and especially not by arming themselves in the face of a fascist pogrom.
