I use the word queer as that is the only one which comes close to labelling me correctly. I hate the word however, Queer.. yuk, and due to this I can see the 'educational' aspect. To a lot of us Queer is merely an umbrella term, which says nothing worthwhile about who you are. It won't tell you the long struggle I had admitting to myself I liked girls, or the homophobia I faced on the streets, or the endlessly, never-ending occasions I had to put myself out there and come out to people I barely knew. Queer just tells you that I'm not straight. But to many self-identified queers, who have sat through gender studies, or marched in solidarity with queer resistance, the word has a long and varied history which tells you everything about who they are. But if the label fits, wear it. If it looks like ketchup, and tastes like ketchup, then it must be ketchup.
I've actually thought about the solidarity thing before. I do use bisexual, in the sense that I would never correct someone who made that assumption. Among a mainstream audience it allows me to be frank about my history without confusing anyone, or allowing anyone to whitewash my previous relationships. Among a queer audience however it doesn't have the same power, and actually takes away from my identity. I'm obviously much more aware of bi issues now, and they're something I genuinely regret my lack of awareness before, so in a lot of ways my social presentation is of myself as a bisexual women.
