Would you go against your race?

In chapter 5,  Wise talked about the essay essay he wrote opposing Israel's supports and funding for anti-black South African organizations. He did so because he thought that, as a group that is being oppressed, Jews should not fund or support oppressing groups that oppress other group. By doing so he receive many negative feedback and threats because he was going against his race. We see this trend of people being look down upon or being seen as traitors when go against their own race or religion? Why is it so hard to acknowledge that sometimes they're the problem even if they are not directly the culprit or aware of it. One great thing the German government has done was to make it a law for everyone to be aware of and not denied the events of the Holocaust and making any Nazi organization and memorabilia/merchandise illegal. By doing so, it creates a common understanding between everyone in that country so people are not fooled again to recreate an event as devastating and as diabolical as that event. although not everyone respects that rule, only a small population does and we see that Germany has less Neo-Nazi or Anti-Semitic organizations than many of its neighboring countries. I think we need to go to that extreme in the U.S. to have change but if we want to obtain anything close to racial and cultural equality, everyone has to realize that they are doing something wrong. First black people have to realize that we're not saints and that certain our actions that we did in the past and that we still do create problems in society. In a way, we are victims of our own actions. Next white people have to realized they have it easy and that they actions in the past and present force black people to commit crimes and other things and that crimes are not only limited to black people. I think realizing and being able to self critic each other without being seen as not a "true black" or "true white" person will facilitate this process.
