If this were a swastika, the SS lightning bolts or even the Iron Cross, yeah, that looks pretty Nazi. Instead it's a skull and crossbones just like every other one used all over the place, including the very cool jolly roger, except this one happens to be Nazi. I didn't know, most people didn't know, he can credibly say he didn't know, and we all think the jolly roger's cool. Dog's not gonna hunt.
