No one is going to make Blacks stop using it or start using it because everyone has an opinion about the word because we're different people. The reason these protests won't work is because it's not enough of an issue to make everyone rally. It's not like the right to vote or healthcare. It's about personal morality/opinion. Asking Blacks to rally around that assumes we all think the same.
Seems to me, if you don't like it then don't say it. If you don't mind it, then whatever. And if a white person says it, educated them or smack them depending on your mood. The white people who say it because of a TV show would have found another way to say it. Hello? Remember when they were quoting Kings of Comedy like it was the Holy Bible? Remember that Chris Rock "Nigger vs. Black people" standup? They have enough ways to say it. I doubt that Boondocks is going to magically change the way we deal with the word in everyone's daily language.
