i really don't want to keep posting in this thread, but i can't seem to stop myself.
first of all, which of these things do you see being practiced in the US or any other first world countries? hmm... non, so i'd say that most of these are cultural issues, rather than religious.
to address your issues... female genital mutilation is NOT part of islam. it's practiced by christians, muslims, and anamists in certain parts of africa and south asia as a CULTURAL practice. how come islam gets blamed for it when christians do the exact same thing? please site koranic verse if you believe otherwise. not hadith, as not all hadith are accepted by muslims, and some sects don't accept any hadith at all.
next, the age of aiesha at marriage is disputed. it is one of the most popular insult to hurl at muslims when trying to make them look bad.

Islamic Questions and Answers: Aisha marriage what age was it?
next, "private parts"... are you referring to hijab? if so, according to the koran, women are supposed to wear modest clothing and cover their chest area with a shawl/scarf and not stare at men. men are not supposed to stare at women. the headscarf, though common, is not actually mentioned in the koran. the veil or burqa is not an islamic requirement or invention, but is required by certain cultures (it came from persia originally).
islamic hijab is no more strict than the dress of orthodox jewish women. are they oppressed? what about catholic nuns?
the vast majority of sikh women wear what would be considered acceptable hijab in most muslim countries. are we oppressed too?
next, woman's testimony... i'll just quote directly from submission.org:
The woman's testimony. is equal only to half of the man's testimony:This is a gross mis-representation. The woman testimony is equal to the man's testimony except in one case only, the financial transactions. This is according to 2:282; [ 2:282] O you who believe, when you transact a loan for any period, you shall write it down. An impartial scribe shall do the writing. ........ Two men shall serve as witnesses; if not two men, then a man and two women whose testimony is acceptable to all. Thus, if one woman becomes biased, the other will remind her. It is the obligation of the witnesses to testify when called upon to do so. ......
Financial transactions are the ONLY situations where two women may substitute for one man as witness. This is to guard against the real possibility that one witness may marry the other witness, and thus cause her to be biased. It is a recognized fact that women are more emotionally vulnerable than men. If the woman as a witness was worth half that of a man, the verse would have stated so clearly. But obviously that is not the case. Women's testimony in all other matters are equal to that of a man or even supersedes his testimony as in the case of a wife testifying against her accusation of adultery, 24:6-10. See also, 65:2, 5:106 and 4:6

polygamy is ONLY allowed if the wife and wife-to-be agree to it. i don't favor it, personally, but it's hardly a muslim invention. hindus and sikhs and jews and christians have all practiced it at one time or another, some continue to do so. even the sikh rehet maryada doesn't say men can only marry one wife, it says "IN GENERAL, a man should not take more than one wife". this would obviously mean in some circumstances it's ok for sikhs to do it. i ask again, are we oppressed too?
ok, i'm really done with the thread now, i'm sure i've left you a lot to read. 
start with Islam (Submission). Your best source for Islam on the Intenet. Happiness is submission to God.-Islam-Submission-Introduction,definition, discussion, debate, laws, justice, human rights, history, terrorism, Jihad, women, Jews, Jesus, Christianity-Isla, it will answer most of the common misconceptions with logical koranic reasoning.
i agree that many islamic majority cultures treat women poorly. so does most of india, central and south america, africa, SE asia... so does a heck of a lot of the US for that matter. let's try to fix our own house before worrying about what the neighbors are doing. 
fateh!
