Honestly think I'm going to use this image as a reaction to every "Platner didn't know it was a Nazi symbol" post...

You statement was "the tattoo predates the Nazis" not that you didn't recognize it.
Platner is also a self proclaimed "WWII history buff" so he would have ABSOLUTELY known a Nazi symbol so recognizable it was used in fucking STAR TREK in the 1960s.
