The Islamophobic media of the far right, and the more subtle elements within the mainstream media, have continued to construct the view that child marriage is exclusively an Afghan problem, and the Islamophobic narrative given as explanation is - it stems from their Islamic heritage, and using crass language, they go on to cite the lone example of Prophet Mohammed’s marriage to Ayesha, and conveniently ignore all the other marriages to much older women.
Throughout large part of the history, this was not an issue; the Christian nemesis did not make much of an issue, as the mother of Jesus, Mary, at the age of 12-14 married Joseph, who was considerably older around the age of 90. Indeed, in the old days, marriage between an older man and a younger woman in her teens was the norm in most societies. In contrast, Western liberal societies view such marriages with scorn, instead the young ones gain the experience by having unlimited pre-marital sex with various partners, a bit like polygamy, but we dare not call it that! According to one government report , almost all Americans are engaged in per-marital sex and there are similar trends in Europe.
