I'm sort of not sure about the re-examining polygamy argument - I think polygamy may be one of those gray areas that needs to be examined by Islamic scholars - in particular in relation to its purpose in today's time and age. Like other pre-modern practices (i.e. temporary marriage or * muta * , slavery). Rules regarding its application should be made more clear to eliminate confusion. In my opinion, certain cultures which continue to live in what may be perceived to be a pre-modern state, polygamy may be valid and applicable even today (this is why I wouldn't write it off).
Roman: "No it's not. It gives the option to have four spouses only to men, not to women. Only one party has the advantange of this 'want', not the both with their respective gender counterparts."
If you limit polygamy in Islam to a 'want' you ignore its purpose, limiting it to a tool for male sexual pleasure and female sexual oppression - which it is not. The reason females are not permitted to marry 4 husbands' lies in the purpose for permitting polygamy in the first place. That purpose is not for the sexual gratification of males. Polygamy is an exceptional marriage permitted in cases where a level of equity can be maintained between wives, where wives agree to such an agreement and often utilized as a tool to deal with contingencies arising from losses in war and consequential widowhood. In a pre-modern era men didn't become widows, they provided for themselves (when their spouses passed on) - the same was not the case with female widows. In many Islamic cultures today men are still the preferred and often the primary breadwinners of the family. Polygamy thus serves as a sort of pre-modern welfare system - providing for widows of war. Women marrying four men also leads to lineal confusion (as Yacoob as mentioned)and consequential legal ramifications, pertaining to inheritance. Who gets what - the most 'probable' son or daughter?
Roman: "why permit something at collective level which can easily be abused and ignored?"
All rules in Islam can be abused and ignored. All rules of any type can be abused or ignored. In the end its the rule-breaker who must face his creator. Rules whether pertaining to monogamous relationships or polygamous relationships are broken. The rationale behind polygamy makes sense if its instituted properly. Lots of good rules can be abused and ignored.
Roman: "For your Afghanistan example, does it mean that the 'exceptional circusmstances' which exist >in one geographical location should lead the implementation of a rule in dozens of other Muslim >counteries where those 'exception circumstances' don't exist?"
Different cultures have different perceptions regarding polygamy. Some are favorable, others not so favorable. Even within Islamic circles. That doesn't undermine the institution of polygamy, since it allows for a degree of flexibility, providing all parties involved with choices. If polygamy doesn't suit a culture it need not be applied. On another note, many Islamic societies are still operating on traditional systems, in which polygamy may be a valid solution in certain circumstances (I'm thinking of some African countries and Afghanistan here, where no social nets exist to help widows or orphans). On the other hand polygamy may not suit the cultures of European Muslims.
Roman: "We can deal with it when it will come (in this particual case), why bother now based on a an >extremly negligible prababality of its happening in undeterminable future?"
We really don't know how negligible that probability is. I'm not an avid supporter of polygamous relationships. I don't know any practicing Muslims who engage in such marriages. I can see where it may provide a benefit. If no injustice is involved in its application, I really don't see any harm.
I don't know if I have anything else to say about this topic. Camille's post on polygamy is similar to my own thoughts on the subject. Its an alternate view on the topic.
