I think I need to emphasize that the Lysistrata tactic was just an afterthought. Perhaps naive. But the salient point remains that the ground truth of Afghan culture will change when the women change it, and if just whispering the occasional radical thought is as far as they can go right now, so be it. There is always some small degree of communication possible -- no matter how oppressive the overall flavor of the culture is -- between husbands and wives. That small degree, whatever it consists of, is the tip of the wedge. Physical sexual consent or lack thereof is not the key issue.
