Well isn't something alike in the bible too ?
Sorry but this child rape argument isn't really one, there where times were similar things were common even in europe like 500-600 years ago.
This koran is about 800 years old, it cannot be adapted to todays social and cultural standards.
As I might update your view in most muslim countries it will be not possible that a nine year old will marry and get deflorated,
earliest age of marriage is between 14-16 or at least 12/13 (it is but it's mostly ignored! towards higher ages),
neither there are exceptions, such as the yemen where this practice might not be as uncommon as it seems.
You see even if muslims say those words are divine, they tend not to follow the koran in word, they adapt and interpret it.
Like what christians have done with the bible, ok anytime there are extremist people.
I think you should make yourself clear about how we came to todays moral and ethic standards.
And you should not let yourself blind with worn out arguments, you can also find similar things in the bible I guess,
but the more you will embrace those old argument against christianity or islam, you will be clueless about a solution.
But yes I also think that there are muslims, which are a threat to western society but I also take extremist christianism into account to be such a threat.
I am also a naturistic nudist for example, and I don't want to have my freedom cut, to be as I am, where I am.**
