I have a friend who got out of the draft during vietnam this way. (not claiming, but actually being gay and admitting it.) He had to go before his town's draft board to plead his case and they then voted whether to believe him or not. By a vote of 3/2 he didn't have to join the army. The deciding vote was a friend of his father, "Joe" who told him that he would vote in his favor but only if my friend would agree that Joe could inform friend's father of what had occurred. Friend had already told his father that he was gay and said "go ahead and call him now if you'd like". Friend doesn't think Joe ever called his father.
