The best approach to counter this sort of propaganda is gather up all the anecdotal evidence, the photographs, the memorabilia, the diaries...&etc...and establish some sort of Museum...a central collection of Vietnam Vets in a single Spitoon-o-rama...
Make movies...like 'Colonel Schindler's List' about some person who protected returning Vets--in any way--from the onslaught of Liberal vile...
Make documentaries...like 'Sgt. Frank's Diary'...
I remember...March 1971...the Oakland, CA Induction Center...the whistling to the tune of...
You can get anything you want...
at Alice's Restaurant...
Exceptin' Alice...
The military who worked there each day came to work in 'civies', changing into uniforms only after they were safe inside the building. Oh, how I bet they wished those stories weren't Out There.
But they are...
Keep reminding them. Don't let them forget...
Even after they're gone...and all that remains is the putrid aroma of self-righteous, Liberal-Fascist scum...
The idea of countering this propaganda by gathering evidence from veterans themselves is a great idea. When the WWII Memorial was dedicated, I added my uncle's name to the list of those who died in the war. At that time, I noticed there was an oral history project in progress which was set up to record histories of veterans of WWII - packets could be requested by veterans to record their histories. It would be great if such a project could be started for Viet Nam veterans, and possibly it could be something that Texas Tech University could be involved in, as the Viet Nam archives are there. Just a thought, and maybe there already is one, but it would be great to have veterans own personal histories recorded and stored for history to counter this propaganda.
