To disregard one's own culture is to be whitewashed. You do this in order to make way for a new culture. Just as you whitewash a wall to remove the original color, you then paint it a new color. White wash is to make way for something new.
..... that thing government/ civil servants and fake advocacy do that reflects the 'whiteness' of politics and all of its oppressive and exploitative practices. One does not need to be Caucasian to be a whitewasher...metaphorically those who paint over messes with a distracting white wash so there is an appearance of cleanliness, resolution and organization. The mess still remains under this thin coat of deception.
