I returned from the Republic of Vietnam in 1969.
1. I was refused a job because the interviewer said that many of us were drug addicts.
2. I was called a "baby-killer" by a girl I met at a party once she learned I was a vet.
3. I was ignored by high school friends who were into that anti-war movement. Some of my "friends" thought that I might go psycho and didn't like having me around.
Most nights in the 70's TV programs like Magnum PI often had as the plot some Vietnam Vet going psycho and killing someone. Most people then thought most of us were crazy thanks to Hollywierd.
You probably know this already, but I have read that Vietnam Veterans are significantly less likely to be under psychiatric treatment, less likely to be on drugs, and less likely to have been in jail when compared to equivalent-aged men.
