I am heartened to hear and see more about white people stepping into uncomfortable spaces to acknowledge, discuss, and learn about their own racism and implicit biases. The burden is on white people, because white people created this toxic environment.
I think it is our challenge to constantly be aware of and address our own privilege, to examine our motivations and actions (or inactions), and to work toward change.
I thought the one man in the Witnessing Whiteness said it best. Liberal white guilt is not enough.
