The implementation of a white supremacist strategy is not limited to the work of white people. Colonialism infuses, in the minds of some Black people, deep-seeded internalized racism. It is easy to find cases where Black and Brown people cooperate with white people in constructing a white supremacist agenda.
It's important to get that out before you start looking at the black people in the room.
This is one of those cases. It's an example of how teachers, within a school system with an overwhelming majority of white teachers (78%), refuse to concede the interest and needs of Black and Brown students and their parents. Their statement indicates their advocacy for their own interest as puppets in a white supremacist system.
