Who predominantly thinks intersectionality is racist? The extreme right. Why? Mostly because if we actually properly applying it means upending the white male cultural hierarchy. When you used to privilege, equality feels like oppression. https://twitter.com/sarahelder/status/1312068241569705984

Those opposed to this are threatened because they have predominantly benefited from the current cultural hierarchy. Does intersectionality propose to replace this hierarchy where another group is instead placed at the top ? No. It simply seeks to demolish hierarchies.

You can read Kimberle Crenshaw's ground breaking legal study on the theory of intersectionality for yourself here. https://chicagounbound.uchicago.edu/cgi/viewcontent.cgi?article=1052&context=uclf. It centers on three legal cases that dealt with the issues of both racial discrimination and sex discrimination:

It laid out, through three legal case studies, that by treating black women as purely women or purely black, the courts have repeatedly ignored specific challenges that face black women as a group, the intersection of gender with race.

Think about Canada's most recent case of brutal systemic racism, #JoyceEchaquan. Was her treatment solely because she was a woman? No. Was her treatment solely because she was indigenous? No. Her treatment was because she was an indigenous woman. #intersectionality

So seriously the only reason people would call intersectionality kooky or racist is that they want to maintain the status quo. And the status quo is not about equality, it is about the white male hierarchy.
