Bi-erasure is the practice of ignoring, denying, or questioning the legitimacy or relevance of bisexuality. Bi-erasure undermines the sexual identities of bisexual people and their community.
Heterosexual and homosexual people, along with bisexual people who are not open or honest about their sexuality, can all contribute to bi-erasure. Bi-erasure can be fueled by biphobia or be unintentional.
Bi-erasure is short for bisexual erasure. It is also sometimes called bisexual invisibility.
