This particular girl didn't want to, but HAD to conform to the strict impositions placed upon her, not primarily by her religion, but because she was terrified of her family finding out.
We tried to tell them that they could dance if they wanted to, as nobody would say anything, but she refused, as she was basically terrified of the consequences.
She had two older brothers, and said that they had already punished her in the past (no details were given) for something she'd done.
Honour beatings and even killings, are not exactly rare in Britain, usually directed against women.
In Afghanistan, before they were jokingly "liberated", women woud regularly be beaten, simply for showing an ankle.
You tell me what percentage of these women are honesly wearing the veil because of their own FREE choice, as opposed to being afraid of the consequences within their own family/community.
If they are brought up from day one in such a fearful environment, I very much doubt if they are supporting the wearing of a veil, purely by FREE choice alone.
