Part V -- Conclusion
There might be a human genetic inclination toward group solidarity, but its worst manifestations are not inevitable. You can feel solidarity with your family, your religious community, your ethnic group, your nation, etc., without hating others. The hating part is a learned attitude. And, as is often the case, fear will underly the hatred.
Both American and Israeli bigots or terrorists have focused on Arabs and Muslims as a threatening out-group. Both the Americans and the Israelis who do so draw strength from a culture that has deep racist roots. In today's U.S.A. many know that this is wrong and so there is a moral position from which to combat this behavior. Unfortunately, it is not possible to say the same thing about Israel.
In the United States the core need is consistent educational and legal pressure against racist behavior both in terms of individual and institutional behavior. When I say consistent I mean over multiple generations, for at least as many years as it took to create the nationwide bigotry in the first place.
If we do not succeed in this endeavor then American Zionists will be proven correct. We in the U.S. will be just like the Israelis.
