Bifobia
A number of women who were at one time involved in lesbian-feminist activism have since come out as bisexual after realizing their attractions to men. A widely studied example of lesbian-bisexual conflict within feminism was the Northampton Pride March during the years between 1989 and 1993, where many feminists involved debated over whether bisexuals should be included and whether or not bisexuality was compatible with feminism. Common lesbian-feminist critiques leveled at bisexuality were that bisexuality was anti-feminist, that bisexuality was a form of false consciousness, and that bisexual women who pursue relationships with men were "deluded and desperate." However, tensions between bisexual feminists and lesbian feminists have eased since the 1990s, as bisexual women have become more accepted within the feminist community.
Nevertheless, some lesbian feminists such as Julie Bindel are still critical of bisexuality. Bindel has described female bisexuality as a "fashionable trend" being promoted due to "sexual hedonism" and broached the question of whether bisexuality even exists. She has also made tongue-in-cheek comparisons of bisexuals to cat fanciers and devil worshippers.
Lesbian feminist Sheila Jeffreys writes in "The Lesbian Heresy" (1993) that while many feminists are comfortable working alongside gay men, they are uncomfortable interacting with bisexual men. Jeffreys states that while gay men are unlikely to sexually harass women, bisexual men are just as likely to be bothersome to women as heterosexual men.
Donna Haraway was the inspiration and genesis for cyberfeminism with her 1985 essay "A Cyborg Manifesto: Science, Technology, and Socialist-Feminism in the Late Twentieth Century" which was reprinted in "Simians, Cyborgs and Women: The Reinvention of Nature" (1991). Haraway's essay states that the cyborg "has no truck with bisexuality, pre-oedipal symbiosis, unalienated labor, or other seductions to organic wholeness through a final appropriation of all powers of the parts into a higher unity." However, the book "Feminist Essays" (2017) by Nancy Quinn Collins states that in the opinion of its author this "is wrong because bisexuality is
a sexual orientation, a harmless attraction some people simply have, not something they try to have or do in order to create organic wholeness through a final appropriation of all powers of the parts into a higher unity. Therefore, I [the author] would say that cyborgs can be bisexual, and cyberfeminism can and should be accepting of bisexuality."
While the general bisexual population as a whole faces biphobia, this oppression is also aggravated by other factors such as race. In his examination of the bisexual male perspective, entitled, "Managing Heterosexism and Biphobia: A Revealing Black Bisexual Male Perspective", Grady L. Garner delves into the oppression that he faces as both a black and bisexual male. He explains that the internalization of negative sociocultural messages, reactions, and attitudes can be incredibly distressing as bisexual black males attempted to translate or transform these negative experiences into positive bisexual identity sustaining ones. The experience of bisexual black males is different from that of bisexual white males. As the demands and tribulations of black bisexual males appear to be comparatively more distressing than those that black and white, homo- and heterosexual individual's encounter, this acknowledgement is important and vital to the understanding of biphobia from an intersectional perspective.
