I think there are two points here for me, mainly because of living and working in Afghanistan, where the Burkha is seen as not so much as a choice, but a matter of life and death.
The first point is that in many western countries the Burkha is viewed as a matter of choice - my right to wear what I like, in accordance with my religious beliefs. The right, or not, to wear it is debated by educated people - those whose lives have always been defined by choice and to whom the wearing of it is seen as a democratic right.
However, in Afghanistan the wearing of it or not is not a matter of choice. Yes, in Kabul most women do not wear Burkhas and in the Women’s Garden (a women only park in the capital) Afghan women will even remove their veils and head coverings. I know women from Kandahar, Jalalabad, Herat etc who remove their Burkhas on arrival to Kabul, because it is a bit of an oasis, at odds with the rest of the country, a place where it is possible to believe that some form of choice exists. However, in the rest of the country the Burkha is not a choice. In Kandahar if you do not wear one you will be killled. In Jalalabad if you do not wear one you might not be killed immediately, but you will be threatened and intimidated until you do wear one. I know this because it happened to a young Afghan woman I know, who did not really want to wear the Burkha in Jalalabad, yet she had continual death threats aimed at her family and herself and now she wears one. The threats are not confined to Burkha wearing - they extend to women working, women getting an education, yet the Burkha is part of it - a symbol here not of rights, but of oppression.
So the Afghan women, across the country, are fighting for the right not to wear the Burkha - which is difficult to see in, hard to walk in and is generally very hot in 40 degree temperatures. It is viewed as something that is imposed and when faced with the choice, in Kabul, many choose not to wear one. However, when faced with the prospect of being murdered for not wearing one outside the capital - women wear it. You don’t wear one - you die.
So, yes, we have the choice here to wear what we like. Yet what we wear may be the symbol of something darker and more repressive (remember Prince Harry and the fancy dress faux pas). We see the struggle to wear it as a democratic right, yet Afghan women do not see it like that. They see it as a lack of solidarity with their struggle, as a slap in the face. I know, because I have spoken to Afghan women, worked with them, socialised with them and they need our understanding of this, because here it is not a matter of simple choice of whether or not to wear a Burkha, but a matter of being murdered or staying alive.
