@Oberon,
And there you already have gone into the trap. The Burkha is not the issue - the mindset behind it making women wearing it, the sexual repression at home pushing them into that role -
that is the problem. Where are your mentioned civil liberties there? Equality of men and women, in your societies at least? Equality before the law? No child marriages? Do you think this sexual discrimination comes to an end just because Burkhas get banned - or replaced with a Hijab or an al-Amira?
Like I say so often, the mindset, the content, the attitude of Islam is the problem. And that does not get tackled by banning certain clothing, or replacing clothing, or issuing a paper with an official stamp on it.
The mindset stays to be there, in this case based on
both patriarchalic cultural tradition as well as religious demands of Islamic ideology.
