Those who salute the gun, 
often salute the taking of lives.

Those who honor the gun, often find honor in taking another person's life. They see the death of their victim as a service to humanity. They have erased  someone from existence, someone who didn't deserve to live. And, in this, they take their pride.

Think of the man who killed so many in the mosques of New Zealand. Was not he a proponent of guns, and did he not think he was doing everyone a favor by killing these Muslims?
