Mills’s three-page-long catalogue of European and American atrocities might be hard for some readers to swallow, and that’s his point: the historical record shows that white supremacy has caused has more death, suffering, and destruction than any other political ideology in the history of humankind. It’s still the reigning ideology in the contemporary global order, which means people still have to reckon with it. But its magnitude explains why most white people choose to ignore or forget about it whenever they can. Although this makes people feel better, it also prevents them from speaking out or taking action against white supremacy. Therefore, although ignorance is common and understandable, it’s also a form of morally reprehensible negligence. It amounts to complicity with both historical and contemporary genocide, slavery, and colonialism. This is because willful ignorance allows white people to continue enjoying the power, wealth, and privilege that they and their ancestors have amassed through the racial contract.
