“Every issue in U.S. society is shaped in a white supremacist fashion,” according to activist and scholar Jeffrey B. Perry, the biographer of early 20th century Black socialist Hubert Harrison and a friend and collaborator with Theodore Allen, author of The Invention of the White Race. Allen emphasized that "white supremacy is the principal retardant to class consciousness" in the U.S. and it is critical that we make struggle against white supremacy a central component of our struggle.
