My point was that the 9 year old thing is not in the Quran so is not an example of the Quran not changing.
To address your point - not sure there are any Muslims who believe that he raped a 9 year old - my impression is that they do not think of it as rape, even if they believed the 9 year old age thing was accurate (and her age has ranged from 9 -19 years) because as part of the belief the story would be that Aisha was not harmed in any way because she would have been protected from harm by God, because she was divinely ordained to be Prophet Mohamed's wife. And given that the traditional stories say she did not have any children with him, she went on to be an important figure in the Muslim/ Arab empire, her words were passed down through generations, and she went on to lead an army after Prophet Mohamed died, not many Muslims apply her unique story to the general public.
Anyone who extrapolates that to mean that in the 21st century they could have sex with a 9 year old who has reached puberty , and believes that God would protect that 9 year old from harm, is likely to be pretty ignorant when it comes to both religion and women's issues, human biology, physiology, psychology, the dangers of childhood pregnancy, the importance of children being formally educated, the importance of job opportunities for young women etc.
What is more likely is that Muslims and non-Muslims who have child brides as part of their culture today do not think too deeply about these issues. Evidence from UNICEF shows that when communities are educated on these issues there are less incidents of child brides.
http://www.unicef.org/media/files/Child_Marriage_Report_7_17_LR..pdfGirls who marry are not only denied their childhood. They
are often socially isolated – cut off from family and friends
and other sources of support – with limited opportunities
for education and employment. Households typically make
decisions about girls’ schooling and marriage jointly, not
sequentially, and education tends to lose out. Accordingly,
lower levels of education are found among women who
married in childhood. In Malawi, for instance, nearly two
thirds of women with no formal education were child brides
compared to 5 per cent of women who attended secondary
school or higher levels of education.
I don't see that blind faith in an idea is specific to religion - certain people cling onto all kinds of non-religious cultural beliefs that cause problems for societies. I think the issue is that some people are not willing to change their cultural beliefs because they have an over-riding emotional attachment to a particular idea or way of life or land.
