Not so much anymore, but back when the war was going on and for a few years after it ended. Vets weren't liked by the general populace because of negative media portrayals, so it was hard for vets to find work. Many were left homeless as a result, and the trauma of fighting a brutal and unpopular war didn't help them keep their heads on straight. This led to many officers encountering crazed homeless veterans, and that eventually became the stereotype. This led to many officers just assuming Vietnam veterans were all crazed war-criminals.
One of America's most recent and despicable tragedies wasn't the war, but how little we cared for the men who needed our love and support.
At least a lesson was learned. Even though the Iraq war was unpopular, the veterans are treated with respect and compassion, and even honor for their sacrifices.
And can you then name an example of a non white character who's entire story is "discriminated against, destroys the entire town, kills the police force, and several civilians as payback" and was celebrated as a tragic hero pushed to far? Maybe one so popular that it spawned four movies and became a household name and part of common vocabulary, and made hundreds of millions of dollars? "Do the right thing" was controversial and derided by the public and critics because they thought it's themes would lead blacks to riot. I dunnoh, I'm just saying maybe it's not tr same thing.
