Ah....the Power of Ridicule!

[Owlix]

In one 'school of though' it's what black people (and some whites like Eminem) can call black people, but what white people (unlike whites like Eminem) CANNOT call black people.

In another school of thought (how I was raised), a nigger is an ignorant person of any race or color.
Mind you, how I was raised was also that it's probably a wise idea to avoid use of the word nigger altogether.
