A veteran's day is designated in November for all veterans.  No difference exists between veterans who have served in the military in any era throughout history.  The blatant attempts to further politicize and dredge up Vietnam as some kind of glorious and patriotic undertaking belies the fact it was based on lies just like Iraq.  The use of Vietnam veterans as political, conservative phony patriotism fodder denigrates those who, for no good reason, had to serve and many who died, again for no good reason.  The war was illegal and inglorious.  Whether your story is true or false, too many such stories have been proven to be false over the years.  Groups of conservative, mostly republican, hacks regurgitate the same mythology to con people into donating to spurious causes promising help for veterans with no such occurrence.  The draft was in place so little choice was allowed for the entire disaster.  Your "disparagement" was very small compared to the millions impacted by it all.
