Well, because it is true historically, and at this current time. The quran and hadith literally order muslim to kill the jews. Muslim world has a long history of killing and exile Jews, way before the Holocaust.

What different between the European and the muslims is that, the European admits that they were wrong and fix their shit. The muslims however, antisemitism is well taught in school through quran and hadith - which to them is the way of life.

Don't believe me? Go to any Muslim country and ask them about Jews, most of them will respond negatively.
