Under the worldwide global system of racism (white supremacy) every nigger is an entertainer.
Notice how the use of the word never sticks to white people. A nigger is a non-white person who is subject to white supremacy (racism).
A black person is taken, under the system of racism (white supremacy), through a process of niggerization. To end this process you have to end white supremacy (racism), through codification, and that is the process of de-niggerization.
