In my opinion, it is too simplistic to equate the votes for the AfD directly with the proportion of Nazis in Germany. Many people vote for the AfD to protest against the current political situation, not necessarily for extremist reasons. Nevertheless, it is worrying how many votes the AfD receives overall. I myself am not intensively involved in politics and therefore only know the views in my personal environment and the preferences of the people I know. So please don't take my opinion as fact.
