Geek culture likes to consider itself pretty progressive. In general that’s a fair assessment: people who feel different or ostracized tend to sympathize with each other, and in this regard geeks and marginalized groups have something in common. In spite of this, however, problems and prejudices that exist in society on the whole do tend to endure in some form even amongst geeks, and biphobia is one such problem.
Biphobia is a constant struggle for bisexual people of any gender in ways that are superficially different, but which stem from one underlying idea: society’s obsession with wieners. Let me explain. In popular opinion, women who are bisexual are assumed to be straight and using their sexuality as a performance to gain male attention. Men who are bisexual are assumed to be gay but afraid to properly come out of the closet. Either way, the presumed be-all end-all is thirst for the mighty D, and geek culture is often guilty of this assumption as well.
