Of course it's unfair to challenge or dispute a fatwa purely on logic. Logic loses against faith every time (refer to my sig
It is in my opinion that the National Fatwa Council is an irrelevant body, that they are issuing ridiculous decree after ridiculous decree in order to gain support of the religious conservative ignorant Muslims and even the not-so-religious, not-so conservative and not-so-ignorant Muslims who are afraid of appearing not as religious as their neighbours.
There are plenty of other National Fatwa rulings that Muslims in Malaysia has ignored. For example, did you know that they have decreed that smoking is haram in 1995, but I still see plenty of Muslim smokers.
But then, that is one of their better scientifically supported fatwas so I guess that people would not want to follow that. This on the other hand is about "protecting the wimmens", so sadly I guess that people would be eager to follow it to the letter
