Arab Muslims drove the East Roman Byzantine occupation out of palestine. the Arab Muslims then left to drive the East Romans out of lebanon, Syria, etc. It then took the locals 200 years to adopt Arabic as their own language. The ONLY Arabs who need to learn how to speek Arabic are Arab baies.

The genetics of palestinians shows that they are no more Arab than the Lebanese or Egyptians or Syrians are Arabs. Arab Muslims are not known to have replaced ANYONE. But Zionist propagandists have the weak minded tools convinced that because Arab Muslims once conquered Palestinian lands that Palestinians are Arabs.
