Did you read the article? There is a not a single claim I make that suggested anything about the words of white people being irrelevant. The point is about making conversation about important topics more inclusive. I don’t want to silence white people, I want to make conversations more robust by amplifying other voices. Maybe give it another read and try not to read things into it that aren’t there.
People in academia ARE “simple ordinary people” and the point of this piece was to highlight one of many accessibility issues in the field. No one needs a fancy piece of paper to do anything but given the history of exclusion in academia, it’s worth discussing the work that marginalized and historically silenced folks are doing to change the landscape of the discipline.
