This New York Times article about the conflict over women adopting Islamic wear in previously secular Turkey is worth reading. The DrsC were in Turkey a month ago and saw lots of women covered from head to ankle, in hot weather. The other DrC has pix on her website, cruztalking.blogspot.com.
It would appear that at least some of the apparent orthodoxy is merely youth rebellion against the status quo. My on-scene observations suggest the Times has given this aspect of the movement too much emphasis. We saw plenty of older women covered up too, no youthful rebels they.
If Turkey loses its secular emphasis and slips into Islamic orthodoxy, a large and relatively developed country will have joined "the other side" in what many of us are calling "the Long War."
