Franz Boas was one of the leaders of "scientific anti-racism" and a fanboy of the Soviets.
The video laments the role of removing of biological realism in political discussions. As we can no longer discuss biological factors, especially differences between races, we are left with attributing all of our social problems to amorphous social factors and most especially to "racism". We know the impact of race but we are marginalized and shut out of the conversation.
It's a pretty solid video, give it a watch and maybe a share if you are so inclined.
