A US university has taken immediate “corrective action” after a professor threatened to discipline students who submitted projects opposing abortion, same-sex marriage. Or the Black Lives Matter movement.

The professor at Iowa State University said the course’s goal was to help students “develop skills in written, oral, visual, and electronic communication.”

The syllabus included a “GIANT WARNING” for students: “Any instances of othering that you participate in intentionally (racism, sexism, ableism, homophobia, sorophobia, transphobia, classism, mocking of mental health issues, body shaming, etc) in class are grounds for dismissal from the classroom”.

“The same goes for any papers/projects: you cannot choose any topic that takes at its base that one side doesn’t deserve the same basic human rights as you do (ie: no arguments against gay marriage, abortion, Black Lives Matter, etc). I take this seriously.”

In a statement to CNN, the university said it took immediate “corrective action” and amended the syllabus.
