I stumbled across this short video quite by accident on youtube and it struck a note. The words below are from the producer of the film. Their site is here
The Vietnam War marked a time of social unrest that divided our nation like never before. Service members returning home with physical and emotional scars were greeted with an unprecedented level of disrespect and dishonor. The courage and sacrifice of our veterans cannot be overstated. When you encounter them, thank them for their service. You never know how powerful those words may be.
