I'm going to repeat myself, since this concept is apparently quite difficult for most white girls to grasp: if you are white, do not say nigga. If you are white, do not say nigga. If you are white, do not say nigga.
Under no circumstances should the word "nigga/nigger" come out of your mouth.
I do not care if your best friend is black.
I do not care if you're dating a black person.
I do not care if you grew up in a black community.
I do not care if you were adopted by black guardians.
I do not care about any reason you give me that could possibly justify your use of the word. It's never okay. Do not say it.
Yes, black people use the word "nigga" frequently and casually. It may seem "unfair" to you to see them use it so freely. (That's what the white girls at my school tend to whine about. They think it's "unfair" that we can say it whenever we want. *rolls eyes*) Whenever it seems "unfair" to you, shut the fuck up and remember hundreds of years of slavery and institutionalized racism. That's unfair.
It's really sickening to see white girls throw around "nigga" so easily. I mean, they're really comfortable with the word and honestly feel like they have a right to use it. And have a prepared mental list of reasons why they should be able to use it. That's crazy to me.
It seems like they're constantly looking for opportunities to say nigga; looking for reasons; looking for excuses. As I've said countless times before, and will probably say countless more times, if you are not black it is not okay to say nigga. Period. End of story. It will never be okay.
The day I allow white people say nigga is the day they decide to own up to the racism and hatred behind the word. It will be the day that they understand that there is dominance behind the word, and that using it belittles every black person that they know. It will be a day that they recognize white privilege, and their ability to embrace aspects about a culture that seem cool, like the word "nigga", without taking on the shitty aspects of that culture, like racial profiling and discrimination. When that day comes, then they can say nigga whenever they want. But until then, I will continue to check every single white girl (and boy, of course) that lets the word slip out of their mouth.
