"According to the theory, those who are most oppressed have access to deeper, more authentic knowledge about life and society."

Which explains the race to the bottom of the victimhood ladder, as the most oppressed is surely the most wise.  It does lead to the question that if the victimized and oppressed have a "superior understanding of the world" - how exactly did they become oppressed in the first place?

"If you have wondered why there are so many millennials on campus telling people to check their privilege, demanding trigger warnings, calling people out for micro aggressions, and retreating to safe spaces, the Factual Feminist has the answer: Intersectional feminism... 

According to the theory, those who are most oppressed have access to deeper, more authentic knowledge about life and society. In short: members of privileged groups (especially white males) should not only check their privilege, but listen to those they have oppressed—because those groups possess a superior understanding of the world...

Now there are social scientists who use a sensible, non-politicized version of intersectionality to understand complex social identities—I have no quarrel with them. But what concerns me is how intersectional feminism is taught and practiced on the college campus. I have many objections—I will limit myself to three.   

Problem 1: It’s a Conspiracy theory

 If intersectionality theory were merely a reminder to be sensitive to different kinds of social advantages and disadvantages, that would be fine. But it is much more than that. It is an all-encompassing theory of human reality-- constructed to be immune to criticism. If you question it, that only proves you don’t understand it—or are just part of the problem it seeks to correct. That is why articles by skeptics almost never appear in textbooks like these. And certain groups—men, for example—are sinners who are marked with a capital P. If they dare to question the theory they will be told to check their privilege. Their job is to atone for their unearned advantages and learn from those they have oppressed...

Problem 2: Victim Creep...

Problem 3: Bullying..."
