If by saying the n-word casually, you mean removing the hatred and power behind a word which has divided our people for centuries by giving it a new and friendly connotation, then of course I am for it.
If by saying the n-word casually, you mean flippantly dismissing decades of institutionalized enslavement and murder, and a constant reminder that for all our progress we are still very much two nations, then I despise it.
Its clear to me though that the n-word still causes a great deal of pain to many of my brothers and sisters, and I want no part of that. So even though I hope that someday the n-word will lose this meaning, you're not going to hear it coming out of my mouth.
