The racist doctrine of "replacement theory" originated on the progressive left. It was first articulated in a 1901 article by Edward A. Ross, a leading figure of the progressive movement and a proponent of racial eugenics.

Ross's 1928 book "Standing Room Only" merges replacement theory with a creepy white supremacist spin on birth control that faults non-white reproductive rates for low wages and a litany of related progressive grievances. pic.twitter.com/jNxzF74j1t

The AAUP connection to Ross is especially alarming because it involved the case that led directly to the organization's founding. In 1900, Ross was fired by Stanford University after he gave a racist speech espousing Aryan nationalism to a labor union rally in San Francisco. pic.twitter.com/CLH6fC8luI
