I could really care less about penises and vaginas when I'm working through a math or engineering problem and I'm absolutely not alone. I've done a tonne of workshops and conferences and the sex of the other students hasn't even popped onto the radar. Either my professional circle is full of Unicorns, or the issue of requiring a dedicated space to foster female solidarity in the face of insufferable male 'intimidation' is one of political invention.
I tend to view intentional partitioning of communities, rather than inclusive interaction, as counter-productive.
