please to keep from causing the outwards directed laughter of loudness whilst I am working, thankyoumuchlyok?

Seriously though, even if there are some evolutionary bases for some of the societally dictated ghender-disparities, so the fuck what? We don't pre-masticate the food for our kids anymore either, or eat our dead rather than waste protein while painting cave-pictures. Whether something had a purpose 50k years ago, I can't imagine that somehow having any bearing on now.
