The Negro people are allowed to say the N word. It’s only unforgivably racist if said by other than the Negro people.
I have warned my negro friends not to use the “n” word. I have explained to them that by using the “n” work, they give former ku klux klan leader David Duke and argument that he can use it, too. A David Duke can say that why should people complain if he uses the “n” word when black people say it all of the time.
