Eugenics, the ideology of arrogance, is generally ignored. Few people even know that the word means. But this ideology led to racism (academic racism), abortion, anti-immigration laws, population control, abuses in genetic engineering -- to mention a few. It is astounding that any serious historian or political leader imagines that it is possible to understand today's world without getting a firm grasp of eugenics! This exploration covers a huge expanse, and cannot possibly do justice to these topics. But it does provide a general picture, and shows how the pieces fit together.
