Islamic family values
Incestuous abuse, of course, is not unique to Muslims, as the horrifying Josef Fritzl case shows (though such things do seem to happen more often, and are certainly easier to hide, in sexually-repressive societies). The rest of the story, however, is telling. Depraved individuals exist everywhere, but social norms really are different in different societies. Even in a strictly Evangelical Christian family in the US, or a strictly Catholic family in Brazil, or a strictly Buddhist family in Korea or Thailand, or a strictly Jewish family in Israel, a father would be vanishingly unlikely to try to kill one of his own children for abandoning the religion (none of those religions mandates murder in such a case). Furthermore -- and this is the real point -- he would not be able to gather a mob of his neighbors to assist him in doing so. That is only possible in a community where murder for apostasy is a social norm.
One of the many disturbing aspects of the story is that once, at school, Hannah Shah did tell a teacher about the incestuous abuse she was suffering at home. The British authorities' response was to send a social worker "from her own community" (that is, a Muslim) who, of course, accused her of "betraying" the community and told her father what she had said. The European authorities' hands-off approach to the Muslim minority's enforcement of its own norms is a major reason for the persistence of the problem which Islam in Europe represents. Shah herself says that many more Muslims in Britain have renounced Islam than is generally realized, but keep silent through understandable fear.
Far more Muslims would probably abandon Islam if their social environment were even moderately more conducive to doing so. I will be posting a longer discussion of this important point in the near future.
