If you're thinking of posting in facebooks comments in defense of this guy: don't.
You cannot possibly make up anything as insane as this. I have no scale by which to measure the breathtaking awful-ness of this: as a father-son bonding thing, picking a Nazi name to live by, interpreting Nazi militarism and aggression through the lens of anticommunism in the Cold War.
He's got defenders. There's a comments thread at the Atlantic. Secondary coverage over at AP (where I first saw it) is tiptoe-ing-ly neutral.
It really makes the idiots making up military records and undercover cop work and etc. seem reasonable by comparison.
