Aversion to lesbianism or lesbians either as individuals, couples or social groups. It can include prejudice, forms of contempt and discrimination or violence against them, whether symbolic, psychological or physical, on the basis of their sexual orientation and gender expression. Lesbophobia is a form of sexism that intersects with homophobia but has specific implications because it involves double discrimination against women for being women and for being homosexual. Thus, lesbians are sometimes subjected to lesbophobic attitudes not only by heterosexual men and women, but also by homosexual men and bisexual people. Bisexual women prefer the term biphobia to refer to the prejudice they face because of their sexual identity, just as certain people who identify as transgender prefer the term transphobia to express the discrimination and violence they face. Lesbophobia, biphobia and transphobia, like homophobia, refer to discriminatory attitudes held by heteronormative sexual identities.
