This is really upsetting. It appears that the idea that biphobia originates from gay and lesbian communities is so deeply ingrained in bisexual* communities many people are incapable of thinking outside it.
To make myself clear: THE IDEA OF MONOSEXISM MEANS THAT IT’S A WIDESPREAD STRUCTURE. IT MEANS IT DOES NOT ORIGINATE IN GAY AND LESBIAN COMMUNITIES. GAYS AND LESBIANS ARE NOT OUR OPPRESSORS (though they may well cooperate with this structure).
Here’s a snippet from my book to help explain. It is part of a much longer criticism of this idea (some parts bolded for emphasis):
The stance that bisexuals are only oppressed as a result of homophobia and lesbophobia erases the need for a unique bisexual liberation struggle and places bisexuals as mere “halfway” appendages to the gay and lesbian movement.

Considering the fact that the overwhelming majority of biphobia and monosexism originates not from gay and lesbian communities, but from heterosexual structures, it seems like the bisexual movement, as a whole, is all-too-focused on the wrong aspect. This overwhelming focus on gay and lesbian biphobia creates a false impression that, as a commentator recently put on my blog, “[bisexuals are] perfectly justified saying we get worse treatment in the gay community [than in straight ones]”. In turn, this notion contributes to the belief that bisexuals do not, in fact, experience (as much?) oppression by the heterosexual society, as well as sprouting the belief that our “real problem” lies with not within heteropatriarchy, but within gay and lesbian communities (that is, scapegoating).
