Harmful, toxic equalism

The first full sentence of the Amazon book review of Nicholas Wade’s forthcoming book:

Fewer ideas have been more toxic or harmful than the idea of the biological reality of race, and with it the idea that humans of different races are biologically different from one another.

One of those putatively few ideas that has been more toxic and harmful is the idea that there are no meaningful biological differences between different members of the human race. As Steve Sailer pointed out 15 years ago, Stalin and Mao killed tens of millions more people in the name of equality than Hitler did in the name of inequality.
