First, Sammy Davis, Jr. was NOT a Jew and did NOT convert to Judaism. He got a Reform "rabbi" to claim he was converted because Davis thought that that would help his career among Jews in Hollywood. Little did he know that the Jews in Hollywood are all assimilated, intermarried, self-hating scum who are not at all impressed by someone who claims to be interested in the Jewish faith which none of them believe in.
For you, as a black man, to lecture the Jews about racism is real chutzpah (gall). Your people overwhelmingly support black Nazi leaders like Jesse Jackson, Louis Farakhan, Al Sharpton, the Congressional Black Caucus, the NAACP, etc. etc.
The Jews fought for you in the civil rights movement and even gave their lives for you (Schwerner and Goodman were killed in Mississippi trying to register black voters). To this day, the UJA and other Jewish establishment Jews fund your anti-Semitic organizations like the NAACP, the Urban League, and so on.
Your people have expressed their "gratitude" to the Jews by backing black Hitlers like Jackson, Farakhan and Sharpton. And by murdering innocent Jews like Yankel Rosenbaum. And black jurors in case after case acquit the murderers of Jews even when the evidence is overwhelming.
Don't come here lecturing the Jewish people about racism. YOUR people are the worst racists and anti-Semites in America. YOUR people are the "Klan with a tan."
