In fact much muddled thinking exists here. The ugliness of bigotry and prejudice relates either to denying a group an opportunity available to others, or giving a group an opportunity unavailable to others. Clearly this is unfair and should excite our indignation. Men for example, remain different from women. Let us agree they should be equal; let us agree one side should not be harmed by the other; let us agree that each deserves to realize their potential and fulfillment without prejudice or bigotry. Nevertheless men remain different from women physically, psychologically and spiritually.
So too, Jew and Gentile. Neither group is to be discriminated against. Nevertheless Jew remains different from Gentile.
