People from authoritarian, male-dominated, punitive families tend to vote for "strongman" leaders and for "hard" punitive policies (prisons, wars) rather than "soft" caring policies (healthcare, childcare). Not everyone from this background does. But many people do. And this conditioning can be exploited, as Trump's campaign did, especially in times like ours of economic, social, and technological upheaval.
That both Muslim fundamentalists and the Christian right are today focusing their attempts to regain control in a rapidly changing world on frantic efforts to maintain control over women, particularly over women's sexuality. Moreover, given their mythologies about "holy wars," it is also understandable that they should use "divinely approved" violence to do so.
The link between intimate violence in the home and the international violence of terrorism and war is as tightly bound together as the fingers of a clenched fist.
It is not coincidental that for so-called religious fundamentalists - whether they are Western or Eastern, Muslim or Christian - rigid male dominance and "holy wars" are priorities. Or that competing sects of the same religion, such as Sunni and Shia, are at each other's throats. In these cultures, women are rigidly controlled by men.
war and the 'war of the sexes' are neither divinely nor biologically ordained.
