Aviv Geffen, 47, is Israel's most famous and successful musician.

With his band "Blackfield" he also became internationally known.

But Geffen not only wants to be perceived as a musician, but is active in Israel as a left-wing activist and advocates peace with the Palestinians.

Above all rappers with anti-Semitic texts annoy him about Germany. 

WORLD:

Do you think that young people in Germany or also in France know too little about the Holocaust and anti-Semitism?  

Geffen:

I think hate is kind of cool for teenagers. Because when you are young you are so stupid.
