"Because racism is so ingrained in the fabric of American Institutions, it is easily self-perpetuating. All that is required to maintain it is business as usual.
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 White supremacy 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 on the same destination as the White supremacists. 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 find themselves carried along with the others."
