well i am a relatively late baby boomer and the culture was such that vietnam was so unpopular it kinda became a guilt by association for returning vets. no doubt it was not just wrong, but insult to injury. nobody i know that served,  went in voluntarily, so to put the responsibility onto the vets was total BS ...i could understand once i grew up more and started having vets become part of the our community. eye opener
  i did not ever  disrespect any one coming back from the mideast - or anywhere. the vietnam disgrace taught me respect and empathy for anyone that faced battle at anytime, you don't reference which era you were in the military. i don't remember the mideastern vets being disrespected - i know the vets got virtually no help ,  especially with mental health issues, from the US government.
