Wouldn’t you agree the philistines were arabs?
Philistines were not Semites. They were related to Greeks.
The Philistines were the “Sea People” who — after a failed attack on Egypt — settled in the southern coast of the Levant/Canaan/Israel. They were Greeks. (I happen to believe that they were the last refugees of the Minoan Civilization.) The Canaanites were native, the Philistines were not.
