I have seen several posts which I do not believe the author knew the title was a derogatory term. When in doubt always check. It’s simple and easy. It better to check than receive a nasty letter from someone of that race. I understand sometimes in literature derogatory terms are used to emphasize the severely of the situation. But there’s no need to put in your title.
About a month ago I was at a book fair in New York City, another author not far from my booth had a book called “The Black B**ch” and I watched a group of African American women wreck his booth, torn up his books, verbally attack him as he was trying to explain it was about a pet he once had. And they told everyone who would listen about the “derogatory term” title of his book. Sure, he got a lot of attention that day but the kind he wanted.
Think about your title before you name your literary work. You do not wish to appear as a pumpkin head in your title. It only takes a few seconds to look up a word and learn the meaning of it.
I looked at it this way…there was no way that guy not knew he wasn’t going to get his behind kicked for that title.
