On May 14, a gunman walked into a Tops grocery store in a predominantly Black neighborhood in Buffalo, New York. The massacre killed 10 people. Beforehand, he had posted a long screed online about Great Replacement Theory, using, among other things, links to a series of genetics studies—peer reviewed, and published in prestigious journals like Nature—as citations.
