Yes. Does not change the fact that the professor is a self-hating racist.
Why should white people, but not anybody else, have to give up their identity?
Let's try this on for size: "The only way then for black people to become part of America (or Europe) is to not exist as black people anymore."
If the goal is to dismantle white supremacy, and white supremacy is white culture
How is this not a racist statement?
… then the goal has to be to dismantle white culture and ultimately white people themselves.
An inherently racist statement. Note that they are not saying to dismantle the concept of race. No, they are singling out white people for "dismantlement". That is racist.
The professor finds merit in the view that the concept of 'whiteness' must cease to exist in order for it to no longer be a barrier to white people's full integration in Africa. There's no self hatred in that. But if you think there is, are you proposing that as a definition of 'woke'?
It is completely self-hating and racist, as is his violent language about "castration of whiteness". That you defend this shows how extreme you yourself are on race issues.
