How did the reception of vietnam veterans by the american public differ from the reception that world war i and ii veterans received?

While the general public was celebrating and treated the WW1 and WW2 veterans well, they were generally angry at the Vietnam veterans, mistreated them, called them names, etc.

The difference between the two was that the WW1 and 2 was viewed as saviors of the world, helping to win a battle that they didn't exactly want to fight, but were dragged in

while, the Vietnam soldiers were losing a fight that they weren't wanting to be part of. (its worse that they were fighting a war the public didn't want to be part of, and on top of that, they were losing)

hope this helps.
