A former professor at the University of Memphis is under fire for suggesting that white people are conditioned to commit mass murder.

Zandria Robinson, who until recently served as an assistant professor of sociology at the University of Memphis, decided to tweet her thoughts on the shooting in Charleston, S.C.

“Waits for thinkpieces about how more mental health services could prevent white people from acting how they’re conditioned to act,” Robinson tweeted on June 18.

Robinson’s Twitter account, that describes her as a “dirty South black feminist sociologist,” and “some babies’ mama,” has since been made private, however screenshots of the tweets were captured by the blog SoCawlege.

This is not the only time the professor has tweeted controversial and racially charged comments.

She has since tweeted that the confederate flag is “the ultimate symbol of white heteropatriarchal capitalism,” and that, “whiteness is most certainly and inevitably terror.”

Last month, Campus Reform reported on several of Robinson’s social media posts directed at white students and professors, including one Facebook post warning white students not to perpetuate the stereotype that black students get preferential treatment when applying to graduate school.

“DON’T YOU EVER LET ME HEAR TELL OF YOU PERPETUATING THESE RACIST LIES AGAIN. NOT EVEN IN YOUR HEAD. NOT EVEN IN JEST,” Robinson wrote. “Because if you do I will come for you. And I will do so in public.”

On Tuesday afternoon, the University of Memphis announced on Twitter that Robinson is no longer employed by the university.

The university did not specify whether Robinson had been fired.

Inside Higher Ed reports that Robinson was not fired, but had accepted a job elsewhere several weeks ago.
