Bifobia

Another form of denial stems from binary views of sexuality: that people are assumed monosexual, i.e. exclusively homosexual (gay/lesbian) or heterosexual (straight). Throughout the 1980s, modern research on sexuality was dominated by the idea that heterosexuality and homosexuality were the only legitimate orientations, dismissing bisexuality as "secondary homosexuality". In that model, bisexuals are presumed to be either closeted lesbian/gay people wishing to appear heterosexual, or individuals (of "either" orientation) experimenting with sexuality outside of their "normal" interest. Maxims such as "people are either gay, straight, or lying" embody this dichotomous view of sexual orientation.
