Plz do not bring a sectarian angle to it. Shiaism itself has undergone many changes over the time.
It most certainly has. We are not like Salafis/Wahabis who are scared of changing times and want time to be at stand-still. Such idealogies have temporary life (so does OIL money btw which is the backbone of this drama).
Islam and its laws are flexible or deep enough to meet the chaning needs of time until the day of judgement. As time passes by, human made laws and systems will keep dying out.
