Well I have no idea if Terry really does have schizophrenia. I believe he has stated he does but I also remember reading that he was not official diagnosed? I might be wrong, please correct me. If he is mentally ill in some way I would presume his use of the word nigger, etc. are related to that, perhaps in a similar way that somebody with Tourette's will use such words?
