In the video below, filmed at the University of Cape Town, members of the science faculty meet with student protestors who wish to “decolonise” the university and not pay their bills. During the meeting, one of the staff, one of the “science people,” points out that, contrary to claims being made by a student protestor, witchcraft doesn’t in fact allow Africans to throw lightning at their enemies. He is promptly scolded for “disrespecting the sacredness of the space,” which is a “progressive space,” and is told either to apologise or leave. The offended speaker, the one claiming that Africans can in fact throw lightning at each other - and who disdains “Western knowledge” as “very pathetic” - then uses the apparently scandalous reference to reality as the sole explanation for why she is “not in the science faculty.”
There being no other, more obvious reason.
