I am extremely sympathetic to this view as an American, but I think it is worthwhile to think of this from a native Frenchman's perspective. There has been a mass influx of "foreign" Muslim/Islamic peoples there over the past twenty-odd years that do not share western secular values for the most part, and are happy to impose their own views on the native population. If you were a native Frenchman, or a person in a similar situation in Europe, how would you feel about women wearing the hajib? I don't think it is that black and white.
