A theater in southern Germany is under investigation after it offered free admission to theatergoers wearing swastikas, and asked customers who paid for their tickets to wear Stars of David. According to the German news outlet DPA , authorities are probing a theater in the city of Constance, after the theater’s website offered free tickets to anyone who showed up to an upcoming performance of a play named after Adolf Hitler’s book Mein Kampf wearing a swastika. The play, which satires Hitler’s childhood, was written by George Tabori, a Holocaust refugee. The theater’s website also requested those not wearing a swastika and paying for their tickets to wear Stars of David "as a sign of solidarity with the victims of National Socialist [Nazi] barbarism." Both the Judeo-Christian Society and the local German-Israeli Society called for a boycott of the April 20th performance. But the theater’s managers denied that their controversial advertisement was motivated by bigotry, instead saying that it was intended to show how people can be easily corrupted. Public displays of the Nazi party symbol are illegal in Germany, and investigators are probing whether the theater could be prosecuted for encouraging theatergoers to wear the banned symbol.
