Ariel Sharon was the son of Shmuel Scheinerman; Amiri Baraka was born LeRoi Jones. Uri Avnery was born Helmut Ostermann; Benjamin Netanyahu's father was born Benzion Mileikowsky. Louis Farrakhan was Louis Eugene Wolcott; Malcolm X was Malcolm Little; Muhammad Ali was Cassius Clay.  Martin David (Meir) Kahane passed, as "Michael King". The differences come after.

An update I forgot to make.

We are living in a time of exploding nationalisms. The blacks in America are the first to abjure the idea of assimilation, to realize the inherent lie in the concept of melting pot. Through black nationalism has developed a new black pride and hence the ticket to liberation

Today’s young American Jew is a good bit slower. He desperately wants assimilation: Jewishness embarrasses him. He finds the idea of Jewish nationalism, Israel not­ withstanding, laughable. The leftist Jewish student is today’s Uncle Tom.
