Aside from how you misuse the word hippie, the Vietnam vets were treated much, much worse by the old writers and TV executives of the late 60s and 1970s, when they were almost always portrayed as mentally unstable and sniper killers.
Did you know that the strongest support for the Vietnam War was from the under 30 age group, an age group that voted 52% for Nixon in 1972?
I don't think I an misusing that tag. They are leftist flower-children.
The ill feelings from that period will probably never be forgotten. They see us as "Lt. Calley", and I see them as "Jane Fonda".
