Incidentally, since you're judging others from such a high horse, when did you serve and what battle ribbons did you earn? Or perhaps you didn't serve at all.
I spent over 7 months in Tonkin Gulf in '72, most of it on the Gun Line doing shore bombardment, and I have the service-connected hearing loss as a souvenir. My ship was one of the 38 that helped throw back the NVA during the Easter Offensive by taking advantage of the fact that their plans had completely ignored the fact that the USN completely controlled the eastern flank of the battlefield.
And, as far as how we were treated by the anti-war movement, I must congratulate you on your selective memory.
