The government-appointed commissioner to combat anti-Semitism, Felix Klein, was criticised in an open letter to Angela Merkel from sixty academics, authors and artists in Germany and Israel. They warned the Chancellor concerning ‘provocative, factually and legally unsustainable use of the term “anti-Semitism”’, saying that freedom of speech is endangered by criticism of Israel’s policies. However many believe Mr Klein has taken his responsibilities seriously with courage and commitment, tirelessly bringing problems to light and demanding concrete action (anti-Semitism in schools and on the Internet, preventing the growth of extremism, and much more). He is the contact person for Jewish groups and social organisations in the fight against anti-Semitism nationally, at federal state level, and in civil society in general, plus promoting awareness of the latest forms of anti-Semitism. He has received support from many different Jewish organisations.
