Can you elaborate on this? IMHO women should be treated equally when it makes moral sense. I.e. women's bathrooms need to be larger because of the various things they need to do in there, not just societal norm things but things like changing tampons, pads.
The menstrual cycle also affects productivity and is essentially a reoccurring medical issue that needs regular treatment.
As for the greater issue being discussed about the male centric nature of hackerspaces and hacker houses, alot of this has to do with proven social psychology facts about how the average man reacts to women that don't fit societal stereotypes. Lots of papers on that.
