Racism is not just about skin color. Here is how the United Nations describes it:
The term “racial discrimination” shall mean any distinction, exclusion, restriction, or preference based on race, color, descent, or national or ethnic origin that has the purpose or effect of nullifying or impairing the recognition, enjoyment or exercise, on an equal footing, of human rights and fundamental freedoms in the political, economic, social, cultural or any other field of public life. (UN International Convention on the Elimination of All of Racial Discrimination, New York, 7 March 1966)
Racism includes prejudice against “national or ethnic origin,” such as the diverse tribes of the Canaanites living within the “holy land” and other groups bordering the targeted territory of the so-called “chosen people” during Old Testament times. The God of the Old Testament is therefore a racist, since he denigrates all ethnic groups except the privileged people whom he considers his “treasured possession.
When the Lord your God brings you into the land that you are about to enter and occupy, and he clears away many nations before you—the Hittites, the Girgashites, the Amorites, the Canaanites, the Perizzites, the Hivites, and the Jebusites, seven nations mightier and more numerous than you—and when the Lord your God gives them over to you and you defeat them, then you must utterly destroy them. Make no covenant with them and show them no mercy. Do not intermarry with them, giving your daughters to their sons or taking their daughters for your sons, for that would turn away your children from following me, to serve other gods. Then the anger of the Lord would be kindled against you, and he would destroy you quickly. But this is how you must deal with them: break down their altars, smash their pillars, hew down their sacred poles, and burn their idols with fire. For you are a people holy to the Lord your God; the Lord your God has chosen you out of all the peoples on earth to be his people, his treasured possession. (Deuteronomy 7:1–6)
