i'm more opimistic about this problem.
i think the latter part of the 20th century and the begining of the 21st will go down in history as the time of the 'reassertion' of faith, and it isnt just with islam, around the time of the islamic revolution in iran the evangelical movement was growing fast in the states.
i belive that as time moves on and technology and access to information become more widespread making peoples lives easier these medievil cultural practises will simply become a thing of the past, this doesnt mean of course that we should put pressure on tribal jurgers and so one that sentence or turns blinds eyes and so on.
there is nothing nice about this next story look away now if your skwimish,
in iran a victim of an acid attack, blind from it, has won the right, under sharia law to pour acid in the eyes of her attacker, the sentence was due to be carried out but amesty international stepped in, the sentence may still be carried out, and soon. this is only one example but the law in many countries we deem backward do take these things seriously, only very remote tribal jurgers in eastern afghanistan and the tribal agencies of pakistan are the places where the truely mind-buggeringly ridiculous sentences get passed.
