I collected some helpful and reliable articles regarding 2:282 , I think this series of posts can help other persons that want to find the truth of this matter in the future and they will find Ourbeacon by google.
This is another good article that I think acknowledges injunction 282 is optional and Quranic State can change it (or again, even two women alone can be taken as witnesses) :
"..The Quran was referring to such women bred in the unnatural way of life, when it said that two women should represent one man as witness. If they are two, the can help and support each other in case they get confused and forget. In other words the second woman is present only to assist the first. Nowhere does it say that in intelligence two women are equal to one man. In fact if women are inherently unintelligent then even hundred women will not be equal to one man.
But this shall not be the case when the Quranic Social Order is established. It will change the whole outlook of men and women, and a new generation of women will emerge. Women will then me ‘created as a new creation’. They will have intellectual and emotional harmony with men ; they will be eloquent and expressive in speech, capable of speaking for themselves and others ‘ the y will be self-confident and independent. Then as witness they will be equal to men. The original injunction there fore fails to apply to this “new creation”. "
«Then as witness they will be equal to men. The original injunction therefore fails to apply to this “new creation”.»
