I'm not sure what LionPride thinks the consequence should be for saying nicca.
Like repeat all you want that non-black people don't get to say it under any circumstances, but how are you going to enforce that.
South Park has had white guys saying it a number of times, in context that it shouldn't be said, but the actors still said it. Louis CK has said it in the same context. Lots of entertainment media has had non-blacks say it in non-derogatory contexts for ages.
What should've happened to them? What is the maximum penalty? A hearty SMH?
