You know, I recently experienced something similar though on a much smaller scale. A friend of mine who isn't a modeler was surprised to find that I had kits of Third Reich aircraft in my stash. He wanted to know why I would "glorify" the Nazi war machine. I explained to him that purely as an aficionado of military history, the Nazi war machine was one of the most fascinating studies, and that study in no way implied any agreement on my part with Nazi philosophies. He found that difficult to understand.
As far as aspiring politicians go however, they should probably forgo donning the SS uniform. It will inevitably be percieved by some as condoning the Nazis and in politics, perception is ninety-nine per cent of the game.
