That kind of stuff is very rarely funny. Perhaps Mel Brooks pulled it off with The Producers... But to go so far as to relate a Star Wars message board's management team, however poorly they a job they are doing, to the SS and the Nazis does a dis-service to the monumental horror of that event and the people affected by it. And it is unfair to almost anyone, particularly people running a toy website.
I'm all for Rebelscum This or Rebelscum That shirts or whatever, but no Nazi comparissons please.
