 These gender cores, supposedly encoding the above traits, however, are nothing more than illusions created by ideals and practices that seek to render gender uniform through heterosexism, the view that heterosexuality is natural and homosexuality is deviant (Butler 1999, 42). Gender cores are constructed as if they somehow naturally belong to women and men thereby creating gender dimorphism or the belief that one must be either a masculine male or a feminine female. But gender dimorphism only serves a heterosexist social order by implying that since women and men are sharply opposed, it is natural to sexually desire the opposite sex or gender.
