vietnam veterans against the war

my biological father was a member of vietnam veterans against the war. my mom was doing civil rights and peace work at the time, and apparently they had quite a few discussions about what was going on.
i have tried to contact all the names on the website about pat, but i have gotten no response. maybe noone remaining there knew him, or maybe they are busy trying to get us out of iraq. word.
there is a genuinely good thing that makes it well nigh impossible for me to find my father, and that is the respect for privacy in the v.a. and im assuming in the vvaw. the vvaw doesnt really say what their policy is regarding things like this, but im assuming that may be why they havent answered me. the v.a. is straight up about their policies involving finding vets. its basically, if we are giving him benefits, or if we know where he is, well get your letter there. but thats all we are saying on it.
i have tried many times to write that letter. its never right. how do you just pop out of a mailbox 36 years later, like "hi, im your son?" if i did write it, he would have no obligation to respond, so i would never know if he had actually recieved it anyway. so theres mystery and drama on both ends. not my steez.
getting around to vietnam, i just read a book called "flashback" which has a lot of terrifying stats regarding vets from nam. did you know more returned vets have committed suicide than all the people who actually died in the war? like, think about the wall. more.
that being said, i know that the odds arent that good for finding him, really.
but far weirder things have happened in all of our lives.
