Lifted from the comments, University of Pennsylvania teaching assistant Stephanie McKellop signals her wokeness to lesser beings: 

That’s this lady here. The one whose areas of expertise include “race, gender and the body,” “self-marriage” and, wait for it, “racial blame.” And who announces, rather proudly, “The classroom is the place YOU get to control the social setting.” A mixed blessing, I suspect. 

Update:

From the pages of Inside Higher Ed: 

Stephanie McKellop, a graduate teaching assistant in history, says she is under attack by fringe-right groups for using progressive stacking in her classes and then tweeting about it. Worse, she says, the university is cowing to such groups instead of supporting her. She’s claimed on social media that her classes were cancelled this week and she may be asked to leave her programme.

According to sociology professor Jesse Daniels, a supporter of Ms McKellop, the negative public response – which included a spectrum of students, educators and parents, of various hues and orientations – is “ripped from the playbook of the far right.” So if you object to overt racism in the classroom, racism framed as piety, then there’s something suspect about you, something marginal. Ms McKellop prefers to dismiss her critics as “white nationalists” and, inevitably, “Nazis.” Readers may wish to ponder how any students who object to this “progressive stacking” policy – i.e., blatant, self-satisfied racial discrimination – will also be designated, and subsequently treated.
