He indicated that Islamicized Germans would have kicket out the racially inferior Arabs

Which is not what would have happened, because under Ottomans (a favourite of the German fascination) every citizen identified as muslim and the rest were slaves, a concept similar to the goyim one, and there was not a concept of racial identity. The Ottoman sultan was recognized as a "caliph" After the Ottoman Empire fell, a cryptojew (Kemal) took reign over Turkey and became Hitler's idol, which is quite ironic:

Under Kemal, the initial concept changed and everyone living in Turkey had to identify as a "Turk" no matter what his actual race was, otherwise he was eligible for extermination, a policy that continued well after Kemal's death:

The difference is that Kemal got away with his crimes, while Hitler who just tried to imitate him is presented as "the definition of evil".
