Biphobia

Biphobia is aversion toward bisexuality or people who are identified or perceived as being bisexual. Similarly to homophobia, it refers to hatred and prejudice specifically against those identified or perceived as being in the bisexual community. It can take the form of denial that bisexuality is a genuine sexual orientation, or of negative stereotypes about people who are bisexual (such as the beliefs that they are promiscuous or dishonest). Other forms of biphobia include bisexual erasure.

The hatred of bisexual women and femmes, being a form of prejudice at the intersection of biphobia and misogyny, is referred to as bimisogyny or less commonly bisexism. This is a gendered form of biphobia that accounts for intersectionality in discussions on bigotry.
