While you are understandably upset, please NEVER compare something to the actions of Hitler/Nazis. It in itself is such a famous and extreme case of negative affect bias (Hitler is bad, Hitler did X, therefore X is bad) that trying to use it only makes your other arguments seem less valid (this, too, is a bias, but its easier to avoid the trigger than try to eliminate the effect). A particularly tongue-in-cheek discussion of that particular example can be found here.
