The prof who seemed determined to dismiss any evidence that returning Vietnam vets had been spit on, and by extension probably that many had been shamefully treated, asked her class of twenty year olds, two generations removed from the war, if they had ever talked to anyone who had personally been spit on during that era. "Isn't that interesting" she said when no one reaised a hand, the not so subtle implication being that maybe the stories were false or at least exaggerated. Doubtless she would have gotten a different result had she gone to some primary sources at a local VFW or American Legion post - but that would have spoiled what she was trying to prove with her "scholarship".....
