Homophobia is observable in critical and hostile behavior such as discrimination and violence on the basis of sexual orientations that are non-heterosexual.[1][2] Recognized types of homophobia include institutionalized homophobia, e.g. religious homophobia and state-sponsored homophobia, and internalized homophobia, experienced by people who have same-sex attractions, regardless of how they identify. Forms of homophobia toward identifiable LGBT social groups have similar yet specific names: lesbophobia – the intersection of homophobia and sexism directed against lesbians, biphobia – towards bisexuality and bisexual people, and transphobia, which targets transsexualism, transsexual and transgender people, and gender variance or gender role nonconformity.[1][3][5]
