The word Palestine is derived from the Biblical denote Philistia, the land of Philistines. Which itself is derived from Hebrew word Peleshet which gets palash that means to intrude. The irony doesn't die because the Sea People were in fact pirates. Also, yes the Arabs don't accept Palestinians. Egypt has especially built a wall prevent the influx of Palestinians.
The OG Israelites (so called Palestinians) were Satanists but here Leftists larp for their authoritarian Religion of Peace.
