Why Is There Biphobia in the Lesbian Community? Why Are Some Lesbians Leery of Bisexuals?
Bi-invisibility is also a form of bi-phobia. If you're dating a same-sex person, you're assumed to be gay, dating opposite, you're assumed to be straight. Even if you come out as bi, people assume you're really one way or the other. Or you just call yourself bi because its trendy or because you haven't made up your mind. All of these are examples of bi-phobia.
Thinking that bisexuals bring STDs and AIDS to the lesbian community is a form of bi-phobia. Using slurs like "fence-sitter" and "AC/DC" about bisexuals is bi-phobia.
Bi-phobia exists both within the LGBT community and in the greater straight world. A lot of bi-phobia is based on myths about bisexuals.
