I’m not sure that qualifies as “posing like Hitler”, give most people a WWII German military hat and they’re probably going to do something goofy. I mean sure, the guy is a douche, but come on, let’s play a little fair.
Not only that, many of the “Nazi” images that James is accused of using (company logo, etc.) come directly from the roots of his business - building hot rods and custom motorcycles. The pre-WWII iron cross / biker cross and the Weimar Republic eagle both figured heavily into the surf / hot rod / outlaw biker cultures of the 1960s (see: Ed “Big Daddy” Roth).
