It is true not all blacks use the n word, but I agree, I won't use the word because I don't want my white friends to use the n word.
Once you make it a practice to use certain words, it gets harder to filter out when to you it and when not to use.
You are better off never using the word if you want to avoid insulting some one.
Many blacks, my age and younger do not have the same emotional outrage when they hear the n word, because the word was never used in a negative way to us DIRECTLY, but there is still a generation of people alive today, that had this word used towards them as the ultimate insult, as a way to make you feel less that human.
If all of us Black and White remember how and why this word was used in the first place, then maybe none of us would ever use it.
I my opinion, maybe Dog's son feels that his dad is a racist, and his use of theN word is just proof of that.
After all, it is his father and let's face it, he knows Dog better than any of us.
