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.
