I hope people were nice to you when you were back in the States. I understand that was not always the case.
Through much of the 70s when I went to a party I didn’t mention Vietnam. People would move away from me. That was when the media were spewing their lies that Vietnam Vets were all time bombs ready to explode. Many people were actually frightened of vets. No one ever called me names. Keeping a knife in my teeth helped. Just kidding.
The funny thing is that no one today will admit they were anti-vet back then. Apparently they were all very supportive. It was always somebody else who did it. Lol.
