Task: Question Answering
Input (English): Passage: Bowie declared himself gay in an interview with Michael Watts for a 1972 issue of Melody Maker, coinciding with his campaign for stardom as Ziggy Stardust. According to Buckley, "If Ziggy confused both his creator and his audience, a big part of that confusion centred on the topic of sexuality." In a September 1976 interview with Playboy, Bowie said, "It's true—I am a bisexual. But I can't deny that I've used that fact very well. I suppose it's the best thing that ever happened to me." His first wife, Angie, supports his claim of bisexuality and alleges that Bowie had a relationship with Mick Jagger.In a 1983 interview with Rolling Stone, Bowie said his public declaration of bisexuality was "the biggest mistake I ever made" and "I was always a closet heterosexual." On other occasions, he said his interest in homosexual and bisexual culture had been more a product of the times and the situation in which he found himself than of his own feelings.Blender asked Bowie in 2002 whether he still believed his public declaration was his biggest mistake. After a long pause, he said, "I don't think it was a mistake in Europe, but it was a lot tougher in America. I had no problem with people knowing I was bisexual. But I had no inclination to hold any banners nor be a representative of any group of people." Bowie said he wanted to be a songwriter and performer rather than a headline for his bisexuality, and in "puritanical" America, "I think it stood in the way of so much I wanted to do."Buckley wrote that Bowie "mined sexual intrigue for its ability to shock", and was probably "never gay, nor even consistently actively bisexual", instead experimenting "out of a sense of curiosity and a genuine allegiance with the 'transgressional'." Biographer Christopher Sandford said, according to Mary Finnigan—with whom Bowie had an affair in 1969—the singer and his first wife Angie "created their bisexual fantasy". Sandford wrote that Bowie "made a positive fetish of repeating the quip that he and his wife had met while 'fucking the same bloke' ... Gay sex was always an anecdotal and laughing matter. That Bowie's actual tastes swung the other way is clear from even a partial tally of his affairs with women." The BBC's Mark Easton wrote in 2016 that Britain was "far more tolerant of difference" and that gay rights, such as same-sex marriage, and gender equality would not have "enjoyed the broad support they do today without Bowie's androgynous challenge all those years ago".
