How do you define this group of people? Most Palestinians have more of the blood of Abraham than the European Jews who displaced them. The idea that the Jews fled Palestine after the Romans conquered it is a myth that can be verified by genetic testing. Many stayed and Hellenized and then converted to Christianity and then converted to Islam. Now these people won't do the rational thing and "convert" back to Judaism to continue to stay in that land because of Pascal's wager and lack of education to see through it. For that, they have their land taken, are excluded from participating in the democracy that governs the country they live in, are starved, and are dehumanized.
"On balance it is fair to state that Palestinians are in fact ethnically Israelite. The divide between the Israelis and Palestinians is on religious and linguistic lines only."
