I can understand the principle of banning in one sense but still don't agree with this as a solution in this case.
The problem with banning is that it may serve to entrench views further, both in 'western' culture and within Islam. It may be seen by some (westerners) as some type of proof that their bigotry, or mistrust of 'foreigners' is justified, or as proof of the 'west's' discrimination against Islam.
At the same time it may make life on a practical level more difficult for individual women.
I think that dialogue is key in helping society to improve the status of women generally (I'm not just talking about Islam). There are great benefits to everyone in society through improving the status of women. The more society realises that, the more things will change. It takes a lot of dedicated work from a lot of dedicated feminists to achieve that level of education among the population though.
Any dialogue needs to be inclsive of women, or perhaps between women alone, initially.
I'm thinking aloud here. Too often women's needs are sacrificed in agreements between men in power.
WLUML is the organisation I was thinking of earlier! Just remembered their site here They are an Islamic women's organisation. - I'm not sure if that link is working. Its www.wluml.org anyway.
Organisations like this may have insights into how cultural stereotypes can shift on a practical level, working with and within communities.
It is right to challenge the practice, but I think the approach needs to be a little more imaginative than simply banning, in this instance.
Its taken me ages to write this so apologies if the conversation has moved in the meantime.
