To fine tune what you said, the article (to leave the actual scientific work in question aside for now) focuses on progressives denying genetic differences between groups, but modern behavioral genetics focusing on differences within groups, between individuals. (Between groups being entirely too muddled by confounding factors) And the stridently progressive crowd (read: Twitter) rage-cruising right past the distinction, and using arguments against the former to dismiss the latter as anathema. And then, as these things typically go, coming to their senses and being somewhat embarrassed by where they end up, but unwilling to concede their obviously righteous point and so making increasingly intellectually ridiculous justifications.
