Dare To Ask Talk And News About Our Differences 
Several answers:
1) Like other whites in America, Jews fear blacks because of the violent crime statistics. I live in St. Louis, which has lots of black crime in the city.
2) I think there's also the feeling that while both groups have been oppressed, the Jews have managed to make incredible accomplishments, especially in medicine, science & literature and the arts - way out of proportion to their percentages in the population. In other words, the Jewish response to oppression is overachievement. By contrast, some blacks seem to use their history of oppression as an excuse for lack of accomplishment. There have been notable blacks like George Washington Carver, but the most famous blacks seem to be those who've achieved in sports, which seems to accrue more benefit to the individual than to society.
