@jojo phil,
Hi everyone... Intresting thread. I spent last winter in Kyrgyzstan living with an Uzbek family (muslim, former soviet union). I don't have a whole lot to comment on the interpretation of this info at the moment, but I figured I'd add it to the discussion...
While burkas are not commonly worn where I was living, head scarves and covering were very common. At the same time, there were mulitple cultures living in the same area, and of course there had been a heavy athiest (soviet) influence for many years, which ended in the early 90s. A lot women there (though no all) have a lot of choice as to how or what they are going to "cover up" with. There are different styles of ramuls (scarves), and different ways of wearing them. As far as I can tell, many of them take a lot of pride in being religious (by wearing the "right" one the "right" way. At the same time I know that they have imense social and family pressure to wear them. There is also a difficult balance to find for the young women as well, who want to be "good" and wear the scarves in very conservative styles, while at the same time wanting to be fashionable, and for at least some of them, the choice was up to them. Until they got married that is, then the husband (and his family) would have a lot of power...
Just some first hand experiences to add to the discussion.
I also have a bit of information that I had heard from those who had recently been, or had friends in, neighboring Uzbekistan. Apperently when the Soviet Union took control many years ago, the women were extremely exited to be rid of the burkas that they had been forced to wear, for a while there were big "burka burning" parties. Now, 15 years or so after the collapse of the Soviet Union, the general populace is returning quickly to more traditional Islam, and apparently the women are in some cases leading the way by voluntarily wearing burkas... This of course was second hand information, but it was believable because I sensed some of the same attitudes where I was.
