I think there's a lot of flack to be had with some of the postmods I know (and I say some because I mean only some!) who would rather see B-F disappear because of its apparent heteronormativity as opposed to embracing its role in diversity. The trouble with disdaining an identity and way of relating to one another (which isn't illegal, harmful or ill-advised) is that it closes the door on education and opens it to the wilderness of propaganda and (horror!) people's "humble opinions" on what they don't really know.
There is a lot of butch-butch and label-free identification where I am because it's a small community and queer/radical visibility is seen as important and necessary in a smaller area. Not being visibly queer as a single femme, I especially feel a double-edged sword in my neighbourhood. It's hard being "the straight girl... is she straight?" at the bar
