I'm not sure I believe the statement that women choose to cover their faces of their own free will. I suggest that they have been indoctrinated from a very early age to regard excessive 'modesty' in women as a good thing and that, because of that, they 'choose' to be among what might be called "the most modest". I think this because it is, in global human terms, such an odd thing to do to cover your face for modesty's sake. What is there to be 'modest' about? Also, why is it only Moslem women who do this, even though it is not a requirement of their religion? Please, somebody, correct me if other people (including men of course) routinely cover their faces in public for any reason other than protection from severe weather or for crimina/dubiousl purposes. Until someone comes up with a truly rational explanation for the phenomenon, which includes an acceptance that human head hair and faces do not need to be covered for some silly notion about 'modesty', I shall continue to think that it's a weird thing to do, it's a terrible thing to make someone else do, and I look forward to its speedy demise as rationality among human beings increases with wider education.
