It sounds like something drunk fratboys thought of.

I think the idea of things like mentoring being with awareness of social and cultural factors, as they exist, and making sure that people are aware that they have been, and can be challenged is good. Still, as a subset of males who are in collage, they may not be involved with and understanding of the ones who are the missing males in their statistics. I know there are major efforts to support and encourage women in engineering. Are they supporting men to enter the underrepresented field of elementary education?

As to the gym discussion, I am curious if the long term existence of Women-safe-spaces is altering the feel of co-ed spaces.
