+1 culture is the problem, I believe.
History/culture/boundaries.
We would be better off dissolving these boundaries.
Boundaries are our major malfunction, I believe. That, and a reduction in the male ego would be a good place to begin our new journey towards a brighter future and would be a welcome step/shift towards something 'better' than this current 'situation' we seem to be in.
I am trying to do that every day :)
