I have started a new book and I am really appreciating what the author has to say. Have you read "Why are all the black kids sitting together in the cafeteria?" by Beverly Daniel Tatum?
She has a great metaphor about supporting racism (or not):
“I sometimes visualize the ongoing cycle of racism as a moving walkway at the airport. Active racist behavior is equivalent to walking fast on the conveyor belt. The person engaged in active racist behavior has identified with the ideology of our White supremacist system and is moving with it. Passive racist behavior is equivalent to standing still on the walkway. No overt effort is being made, but the conveyor belt moves the bystanders along to the same destination as those who are actively walking. But unless they are walking actively in the opposite direction at a speed faster than the conveyor belt – unless they are actively anti-racist – they will find themselves carried along with the others.”
