It all seems to revolve around this attitude:
Whats so wrong with a bit of fancy dress?
Whats so wrong about white, privileged students who belong to a country with a history of systematic oppression of black people and other non-white races, mocking the very people who have most felt and are still feeling the lingering effects of apartheid?
Whats so wrong about women who, due to factors they have no control over, have had access to resources, support, and education opportunities that helped them become students in a University; mocking women who, due to factors they have no control over, did not have the same opportunities and have had to become domestic workers just to get by?
Whats so wrong about well-off people making fun of people who are less well-off?
Whats so wrong about white women turning a black womans appearance into a caricature?
In a world where beauty is so thoroughly anglicized and whitewashed, dark-skinned women feel a constant pressure to try look as close to white as possible, whats so wrong with white women actively mocking the bodies of black women?
Whats so wrong with privileged white women, in South Africa, in this world, with this worlds history and historical treatment of black people, treating black women as comedic, a joke, a funny fancy dress?
It should be glaringly obvious whats wrong.
Blackface, especially in this country, especially with our history, says, louder than words:
We think youre a novelty. We think youre a joke. We do not consider youre worthy of respect. We do not think your feelings matter, or need to be considered. We do not view you as our equals.
Even now, we view you as beneath us. We view you as our entertainment, our slaves, our toys, to mock and imitate while you clean up for us.
If we upset you, if we hurt you, if oppress you, tough. We will tell you to "get over it". We will tell you it's "just a joke", because we consider everything, even bad jokes, more valuable than your thoughts, than your emotions, than your well-being, and than you.
If you dare to complain, we will remind you of that as loudly and offensively as we can.
There really is a mind-numbing obliviousness that comes with privilege, and this reaction, this wide-eyed whats the big problem? response, is the perfect example of that.
