I wasn't trying to mount a high horse, but will continue to point out some flaws in your reasoning for the sake of discussion, and not in an attempt to start any sort of argument.
-Just because you have German heritage does not entitle you to make light of things that occurred there. Germans to this day have to deal with the psychology of the 'guilt problem,' where the future generations still deal with the negativity surrounding Germany due to its past actions. Any form of nationalism there is to this day looked upon with raised eyebrows, unless it is surrounding soccer/football. I've had great discussions with Germans over nationalism, while I have a great sense of pride in my nation, only to find that many are, in some sense, still ashamed of things they were not responsible for.
-Any studier of German can tell you that the word führer can still be found within the language today, in words such as Reiseführer or Geschäftsführer, just as two examples. Never will you see the word simply as der Führer anymore. The word alone simply has that one connotation, and I haven't seen used as a stand alone word outside of the Hitler context. The word Fräuline is also no longer used.
-Although my dog's farts cannot clear a room, they do smell like some pretty nasty seafood.
I guess my overall point is that I understand an American sitting here making jokes about the Nazis, etc., but I wish more people would realize the severity of the issue as it relates to Germans in the world today. Many still carry a heavy burden with them when it comes to this subject. An interesting fact illustrating this is although free-speech and thought is rampant in modern Germany, to this day, the display of the swastika and and nazi/neo-nazi propaganda, uniform, etc. is strictly illegal. Movies and video games from foreign countries, such as the US often have swastikas edited out.
