You, sire, just fucking pissed me off.
First of all, ever heard of freedom of speech? ok, good. Now, you may not agree with me, and you know what, i don't even fuckin care- because i need to get this out there.
Why the fuck are people so concerned about being so goddamned politically correct? I have several "African-American", as PC'ness forces me to say, who will use the word nigger as a way of identifying me when they are talking to me, and dont really care that i use it either - wanna know why? Because they are fucking using it right there, and if there is THAT much of an issue with the damn word, then even "African Americans" wouldnt use it.
That brings me to my next point - the term African American is pretty much racist, because its taking on the ignorant assumption that AAAAAAAALL black people come from Africa, not so.
Anyway, i don't know what in you made you take on the role of saint of Newschoolers, but if you really want to do something, this isn't the way. Instead, set the example yourself, call people out on an individual basis, in a PRIVATE manner. Then you can get an intelligent conversation going, and explain your viewpoint, then the other will explain why he doesnt feel like its that big of a deal.
anyway, go fuck yourself, and have a shitty day!
