I think a lot of that has to do with how in Vietnam they killed babies - and most importantly, heard uncontested stories of this sort of this from everywhere and most did nothing to stop it. It'd be nice to blame this on something nice and tidy, like the public and their darned perceptions, but I think it's because Vietnam was just a dirtier war. (At least morally dirtier than much of what WW2 was for the common soldier, for instance.)
