Yep, MB actually has a point here. MB appropriates women's oppression to centre MBself and is rightly criticized for it.
But MB is a person of colour, and therefore completely entitled to speak about racism and the systemic privilege of white people. You might not find it a comfortable topic, but complaining about how well made the argument is, or how MB shouldn't be angry or some shit, is exactly what men do when they tell women to shut up too.
So, mark the moment, cos it won't happen again unless MB drops the misogyny, but I completely agree with MB's anger and points on this topic.
