"if you speak of "all the nations that descended" out of Ishmael's loins, you'd have to includeArmenia, the first Christian nation in history (it declared itself a Christian Nation in 300 AD),
as well as the once-majority (pre-Muhammad) Christians of Egypt, the Maghreb and Levant (Christian North Africa, once the ecclesiastic province of 200+ Christian bishops),
Anatolia (present-day Turkey), Chaldea (present-day Iraq), Lebanon, etc."
You're forgetting the earlier lines from Noah's sons.
Abraham is from the line of Japhet.
But you also have the line of Shem, and the line of Ham.
Seven Sons of Japheth (see map below): 1. Javan (Greece, Romans, Romance -- French, Italians, Spanish, Portuguese)
2. Magog (Scythians, Slavs, Russians, Bulgarians, Bohemians, Poles, Slovaks, Croatians)
3. Madai (Indians & Iranic: Medes, Persians, Afghans, Kurds)
4. Tubal (South of Black Sea)
5. Tiras (Thracians, Teutons, Germans, Scandinavian, Anglo-Saxon, Jutes)
6. Meshech (Russia)
7. Gomer (Celtic)
Five Sons of Shem (see map below): 1. Elam (Arabia)
2. Asshur (Assyria)
3. Lud (Lydians)
4. Aram (Aramaic, Armenia, Mesopotamia, Syria)
5. Arphaxad (From which Abraham descended)
Four Sons of Ham (see map below): 1. Mizraim (Egypt)
2. Cush (Sudan, Ethiopia)
3. Put (Lybia)
4. Canaan (Hivites, Jebusites, Arvadites, Girgashites, Amorites, Arkites, Sinites, Hittites, Sidonians, Perizzites, Zemarites)
TABLE O F NATIONS (70), Ham, Shem & Japheth
Your map there doesn't even take you to the Indus, and the most populous Muslim nations in the world are east of the Indus. Moreover, the earliest Christian communities were overwhelmingly of the Semitic and Hamitic descent (if you want to shoehorn it into your classification system.) Like, so what? Christ breaks down all the walls of division (Eph. 2:14)
If you want to retain your intricate racial beliefs, which purport to link racial inheritance to moral temperament and national destiny, then I advise you not to look into actual population genetics, because your whole scheme will fall apart.
So, back to earlier points:
- Ishmael was not a Muslim.
- And most Muslims do not spring from Ishmael's loins.
Sorry about that.
