The ugly truth about hate is that it is a cancer that infects all people regardless of color. I bet the liberal blacks are what drove Jacobs to the GOP. Many Southern Blacks are do harbor anti-semetic feelings (remember Billy McKinley & Earl Hillard).
Not just Southern Blacks, it’s an epidemic in the Black community, and has been for a long time. The anti-Semitism/anti-Zionism of ultra-RINO Senator Chuck Percy in Illinois helped him carry heavily Democrat Black Chicago precincts over Roman Pucinski when he ran for reelection in 1972, probably one of the most egregious examples. Fortunately we showed trash like that the door, but at the cost of replacing them with Democrats (in the case of Percy, Paul Simon — in the case of downstate buffoon “Arafat’s best friend in Congress” Paul Findley, Dick Durbin).
