I am not a Turk but will speak for them. In fact- havent met a Turk who read Snow, except my wife to whom I passed it along.
While a lot of the juxtopositions are hauntingly accurate-- the suicide girls for example illustrates not only a true phenomena but the herd mentality so common here-- Turkey, as a 'fast moving' country has gone beyond a lot of the police state feeling that is present in Kars. I would say that the main characters -- Blue, Kadife, the father, the actors, the kemalists, the religious students all represent clear parties in Turkey today. For example- our university is overrun by these ex-religious school students whose rthetoric matches quite closely the fictional version he creates. But, this stuff is largely invisible at first glance.
Sorry, not so coherent, but I gotta class.
