Should all the world follow sharia law?

on oct. 30 2008, the u.n condemned the stoning death of aisha duhuowa, a13 year old girl who had been gang d and then sentenced to death by a sharia court for fornication [zina]. she was screaming and begging for Mercy, but when some family members attempted to intervene, shots were fired by the islamic militia and a baby girl was stoned to death. now! sharia law; the rapist will be punished by death if force on the victim is proven; now! how !can force be proven on the victim be proven? the answer must surely rank as one of the most insane laws in human history. ;; proof of zina [adultry or zina bil-jabr [] liable to hadd shall be one of the following;the accused makes a confession, or there is at least 4 muslim adult males witnesseses. ''punishment will take place when zina or has been proven by witness; sharia law rejects the witness of women in hudood cases' the evidence of women is orginally inadmissible on account of their account of their weakness of understanding and want of memory and incapacity of governing. so how many people would love for the world to live under laws like this; they are hundreds of sharia laws like this; so why do muslims love them? ex muslim?
