I used to say the n-word a lot, but I still claimed I wasn't racist.
Why did you use this kind of language if you weren't racist?
I was uneducated about the use of the word.
It seems that you understand now that the use of this kind of racial slur is wrong because it's very offensive to people. I'm glad you stopped the habit of using this word.
I stopped but I still use the word sometimes.
The n-word is one that you shouldn't use ever. It's offensive and there's really no need for it. People are likely to think poorly of you for using it, too.
