Diary of an "N-Word" - Autobiography

As a writer, I am dismayed by the lack of enthusiasm book agents and publishers have shown toward my latest manuscript titled "Diary of an 'N-Word' ". This very important untold story of what a young "colored' boy experiences growing up in the 50's in New Jersey--not the South--invariably is rejected by agents and publishers with the reply, "It's a compelling account but not right for us." I want to self-publish my book to give a personal account of history that won't be found in our traditional history books, and with my experience on talk radio and TV, I am able to effectively promote it as I have done for other books I have written (Follow The Right Leader, Jack In The Pulpit, Come Die With Me).
