A good example of this neglect is the denialism surrounding the bisexuality of one of the greatest modern black liberation heroes: Malcolm X. The lack of recognition is perhaps not surprising, given that some of his family and many black activists have made strenuous efforts to deny his same-sex relationships and suppress recognition of the full spectrum of his sexuality.

Malcolm's complex, changing sexuality was never part of the narrative of his life until the publication of Bruce Perry's acclaimed biography, Malcolm - The Life of a Man Who Changed Black America.

Perry is a great admirer and defender of Malcolm X, but not an uncritical one. He wrote the facts, based on interviews with over 420 people who knew Malcolm personally at various stages in his life, from childhood to his tragic assassination in 1965.

He documents Malcolm's many same-sex relations and his activities as a male sex worker, which spanned at least a 10-year period, from his mid-teens to his 20s, as I described in some detail in a previous article for the Guardian. Although Malcolm later married and, as far as we know, abandoned sex with men, his earlier same-sex relations suggest that he was bisexual rather than heterosexual. Abstaining from gay sex after his marriage does not change the fundamentals of his sexual orientation and does not mean that he was wholly straight.
