JA is an antisemitic and anti-White racist infamous for his occasional attempts to tar Jews as massively involved in the oppression of Blacks. Here he tried rather unsuccessfully not to sound that charge bluntly. For the uninformed, this accusation originates in a an antisemitic NOI text.

Had the Arab leadership in the Land of Israel accepted the 1947 UN Partition Plan or its predecessor, the 1937 Peel Partition Plan, and refrained from trying to commit genocide on the local Jews, no "Palestinian" would have been dispossessed.
Of more importance, many of the 1948 Arab refugees either left of their own volition or fled, rather than being driven out by Zionist forces. Proof exists, but JA naturally would rather you didn't know of it.
