Women and men are different -> This justifies different outcomes in certain areas such as tech but promotes diversity due to the fact that they think different and could provide a much needed alternative viewpoint in a homogeneous environment. (this is mostly my perspective)
Women and men are the same -> Then there is a problem with the outcomes being different but the diversity argument goes away because men and women view and interact the same. If this is true we have to forcefully equalize all professions to 50-50. This also doesn't make sense in the context of leap - if men and women are the same why do we need environments that are for one gender or the other?
As far as bootstrapping less masculine communities I'm all for that but the execution of it might turn a bit bizarre when you start letting men in.
