If someone hates me I lose more than hating then back. You can use injustice as a motivator in a way that you can not use hate. There was injustices committed by Black make slaves to Black female slaves did that improve the situation?
I don't think anyone us powerless. Ghsndi, King, Mandela and Shabazz priced thus to be true. Their love and self respect were and ate powerful weapons against a grids injustices. That is my belief, as always you are free to believe otherwise. And it doesn't make either belief more valid.
