True, there are Muslim Arabs, and Christian Arabs. But with the exception of Nonie Darwish, Joseph Farah, Brigitte Gabriel and Dr. Wafa Sultan, they have a murderous hatred of Jews. Many so-called Christian Arabs light candles in their churches to Hezbollah leader Hassan Nasrallah. And those Maronites in Lebanon were right there with the Moosies celebrating the release of that monster Samir Kuntar.
Also, your argument about Israel displacing the "indigenous" people is neither here nor there. The Founding Fathers of America were not indigenous people, as the Indians were. And there was plenty of displacement of Indians going on. Does that mean America as we know it, with its Constitution should not exist? Most people would say no. However, your type would hold Israel to an impossible standard not applied to other countries, and you would say, YES!
Also, if Israel committed that dreaded ethnic cleansing, why were there about 700,000 Arabs left in Israel after 1948? And why has the population grown to several million?
You need to stop drinking the Kool Aid.
