don't be so quick to believe that this ever happened. I still do not.
It's easy for someone to say they are a vet of a war. It could easily have just been a pissed off Commie from the 40s who decided to make this soldier feel like crap.
I believe it happened. As I recall the WWII vets in the various veterans organizations had a big resentment against Vietnam veterans for some reason. We weren't always accepted as "real" war veterans. Also, there was a whole lot of misinformation and bad press about Vietnam veterans back then, and many people tend to believe the t.v. and newspapers as though they're gospel.
I thought of that right after I hit "post," and smacked myself in the head.
It probably didn't happen...but please note that I've had a peacenik veteran of the Korean War call me a coward and other assorted names because I have the gall to have an opinion on the Iraq war without being a combat vet. It takes all kinds, and we know that genuine war heroes like McGovern were hardcore antiwar types in the vietnam era, so all it would take for this story to be true is for a McGovernite to be a prick. That's not too much of a stretch...
But you're right, and we should assume it's untrue, because we only have the word of a liar as evidence.
