It's advice on how to fight this war. There's really no parallel between the left and conservatives, Horowitz warns in the pamphlet. For conservatives, politics isn't religion. It's more of an unpleasant duty. Politics is only one part of their lives.

It's arrogant to think that white folks get up every morning thinking what can we do against black folks today. They'd be amazed that whites aren't thinking about black people at all. Time magazine's editorial board apologized to Horowitz about the Aug. 30 column denouncing him as a bigot. But the viciousness of White's column did support Horowitz's contention that the left is blinded to reality, common sense, and decency by its adherence to an outworn faith. They may have betrayed their country out of ignorance, or out of misplaced ideals, or because they were blinded by faith.
