Completely false. There was a fight for Palestinian Arab identity much earlier, separate from just an Arab identity. You are very dishonest.
"Following the arrival of the British a number of
Muslim-Christian Associations were established in all the major towns. In 1919 they joined together to hold the first
Palestine Arab Congress in Jerusalem. Its main platforms were a call for representative government and opposition to the
Balfour Declaration.
The Faisal-Weizmann Agreement led the Palestinian Arab population to reject the Syrian-Arab-Nationalist movement led by Faisal (in which many previously placed their hopes) and instead to agitate for Palestine to become a separate state, with an Arab majority. To further that objective, they demanded an elected assembly.
[33] In 1919, in response to Palestinian Arab fears of the inclusion of the Balfour declaration to process the secret society
al-Kaff al-Sawada’ (the Black-hand, its name soon changed to
al-Fida’iyya, The Self-Sacrificers) was founded, it later played an important role in clandestine anti-British and anti-Zionist activities. The society was run by the
al-Dajjani and
al-Shanti families, with Ibrahim Hammani in charge of training and ‘Isa al-Sifri developed a secret code for correspondence. The society was initially based in Jaffa but moved its headquarters to
Nablus, the Jerusalem branch was run by
Mahmud Aziz al-Khalidi.
