Comment: Everybody that disagrees with you is "non-human," right Jimbo? Therefore you  can kill them with a clear conscience, whether it be a Vietnamese patriot defending his country against brutal invaders from thousands of miles overseas, or someone who went to prison rather than participate in mass murder for lies?  
I served too, Jim, and worked at a group home for pre-delinquent kids when I got out of prison. I've got over ten years in as volunteer firefighter/EMT, Search & Rescue Hasty Team member, and Red Cross first aid/CPR instructor, among other volunteer work. So get down off your high horse. You did what you thought was right, even tho' your boss, Sec'Def' McNamara later said the Vietnam war was a "terrible mistake." You are aware the Gulf of Tonkin incident never happened, aren't you? Does that matter to you, or were just a high school bully that enjoyed harming other people and liked getting paid to do what you loved in Vietnam? Is it guilt that feeds your anger? Time to repent.
