Deir Yassin was not officially sanctioned by the main Jewish militia, the Haganah. That was 100 people on the road to Jerusalem causing problems with travelers whereas Hamas has been terrorizing people for years and then recently had an all out marauding bloodbath 12x as bad as the one you cited. This leads me to believe that the Arabs were not liked because they are hostile. They break the treaties like the recent cease fire and cannot be trusted. Jews have always had a presence in Israel. Arabs are from Arabia and were supplanted their by the Ottomans and Romans.
