I doubt very much Passover is the source of Israel's misgivings about Egypt.... I believe it has more to do with the Muslim Brotherhood gaining power and not on our ancient hatred of the Egyptian people... In fact no where in recent history has the exodus been used as proper bases to hate Egypt or it's people.... so though I appreciate your article... I see no relation between the exodus and Israel's current relations with Egypt. The Passover sedar is a celebration of freedom and no where during the ceremony does it say to hate the Egyptians for happened (or did not happen) in the past.
