Not a Vietnam Vet, but I did get spit on and labelled a killer of babies, amongst other things, while wearing the uniform in the early-mid seventies. No myth, all fact. Every Vietnam Vet I've ever served with has a story similar or worse. This was a universally accepted practice by the general population of youth and young "adults" at the time. Another sorry attempt to revise history to meet a leftist agenda.
I wonder why so many in our generation were/are so stupid.
