"Nigger" (nigga) is and will always be a profane, disgusting, derogatory and perverted word/term.
There shouldn't be any beauty/pride in identifying oneself by a perverted word/term created by their race of people oppressor and enemy. The/our Ancstrs don't have any pride for their descendants in that regard either.
Black & Proud/Beautiful, not nigger/nigga & proud/beautiful.
