I dont think you really understand the kind of thing that would go on there.
i think he's pretty damned understandy. really, i do.
he just (wisely) doesn't feel that making a load of men disappear in a puff of smoke, would solve this problem.
what about the women left behind who depended upon and loved these men? do you think these women would suddenly happily frollick outside to their cars, unburdened by their chains which had been put on them by their fathers, brothers, sons, etc, and drive merrily around in some kind of middle eastern utopia?
cos that's not how it'd go. they'd still be exactly the same women- with the same pasts, learning, experience, behaviour patterns, etc. after most of them had starved, fought, floundered, or otherwise watched their society crumble somewhat, and struggled to get their heads around the enormity of what'd happened, other people would fill the gaps left by those men, and things would continue on in a relatively similar fashion- only with a whole shitload of traumatised women who had lost sons, brothers, fathers, cousins, uncles, etc- men who might have had their heads up their arses in some respects, but whom were otherwise rather uh.... present, and loved.
many of the women in that society may actually share the belief that they shouldn't be allowed to drive. they've been indoctrinated to believe so. should they be vanished in a puff of smoke too? or just brainwashed into changing their minds- to seeing things the 'right' way- the western way?
you don't solve a problem by killing people off.
certainly not by killing them off based upon their gender. you solve it by
educating them, and their children- the problems solve themselves, long term.
