The term `Aryan’ originally designated the region later known as Persia as the point of origin from which all human branches would spread. It was replaced with “Indo-European” when `Aryan’ got its Nazi taint. But the Shah of Iran was also known as “His Aryan Majesty”.
It appears that the Indo-European theory of human origin has been replaced by the east Africa theory of Dr. Leakey & others.
Anent your post, Arabs are ethnically classified as Semitic Caucasians. The point of this thread is the Nazi-influenced origin of the Muslim Brotherhood, and the continued warm regard for the Third Reich (”O Hitler of blessed memory”) in the region.
Given the Jew-hatred that is a central tenet of Islam, and the reality of the Holocaust carried out by Hitler’s minions, it is probably safe to say that Islam & Naziism go together like sugar and tea.
Throw in the history of the Arabs having had their @sses handed to them repeatedly by the hated Jews in Israel, and the Islamo-Fascist hate brew reaches the superheated boiling point it has been at for more than six decades.
