Alice Mitchell was a case study? Was she not a person? You mean she was the subject of a case study? How does that fact, in in itself, establish a causational relationship between the events of her life, or the relating of them, and the maintenance of the privilege of white men?

Meanwhile, I'm not questioning Duggan's research, I am asking on what basis, by what understanding of evidence, or proof, (and more importantly, disproof) it justifies drawing the kinds of conclusions you attribute to her.
