Re: crafted in the style of African American English (AAE)
However, without challenging your primary point about whether words should be removed from the language or not, I will state that allowing or disallowing use of a word based on the skin colour of the person using it is textbook racism.
Nobody I work with will be using the word nigger in the office, because I'll be stopping that immediately. That goes for nigga too, as that's frankly the same word; changing the spelling doesn't change the social acceptability.
