I did not call you a Nazi.  Rather I compared your authoritarian style behavior to that of the Nazis which is a fine distinction.  I did not offer a personal attack as your chosen behavior is relevant and not an irrelevant personal characteristic such as your religion or ethnicity which I never mentioned.  You are in your right to 'remind me' that you feel it is a bad thing to do, but threatening to ban me is out of line and frankly not very productive.
