I did not compare the wearing of a burka with wearing a swimsuit in an art gallery, as you very well know. I said that we all conform to expectations of dress. That isn't very hard to follow.
There are plenty of Muslims,men and women who abhor the wearing of the niqab. Unfortunately they have no influence with the hard liners. For women in those communities, the pressures to conform are overwhelming.
Bags, yes, the stares and comments which girls and women are subjected to are dreadful. But it's men who need to change their behaviour. Not women who need to shroud their faces.
Sadly, certain groups of men, some Muslim, some not, have found this a very convenient peg on which to challenge structures and systems on the piggy back of a woman's right to wear what 'she' wants.
