There is no excuse for these 1,152 page textbooks.

Christopher Columbus introduced two phenomena that revolutionized race relations and transformed the modern world: the taking of land, wealth, and labor from indigenous people in the Western Hemisphere, leading to their near extermination, and the transatlantic slave trade, which created a racial underclass.

Textbooks are written in an oracular monotone, so that they claim to be true and important.

So long as our textbooks hide from us the roles that people of color have played in exploration, from at least 6000 BC to the twentieth century, they encourage us to look to Europe and its extensions as the seat of all knowledge and intelligence. So long as they say “discover,” they imply that whites are the only people who really matter. So long as they simply celebrate Columbus, rather than teach both sides of his exploit, they encourage us to identify with white Western exploitation rather than study it.

The world, of course, doesn't come divided into disciplines. The world just is.

Taking ideas seriously does not fit with the rhetorical style of textbooks, which presents events so as to make them seem foreordained along a line of constant progress. Including ideas would make history contingent: things could go either way, and have on occasion. The 'right' people, armed with the 'right' ideas, have not always won. When they didn't, the authors would be in the embarrassing position of having to disapprove of an outcome in the past. Including ideas would introduce uncertainty. This is not textbook style.

We preach democracy while supporting dictatorships.
