From Tom McLaughlin’s blog:

James Fisher said he couldn’t attend classes at the University of Pennsylvania because one his white professors refused to denounce his white privilege. Fisher is black, and he wrote an article about his mental anguish published in his university’s newspaper The Daily Pennsylvanian. “I stopped going to his class for a month. With different emotions going through my head from not only this class but from the Trump election, I did not want to step foot into another white space until I made sure that my mental health was restored,” Fisher wrote.
