I don't see an image of women getting mistreated. Many women choose to wear these black robes. It is a part of their religion.
A lot of women get mistreated in EVERY colour, creed or religious belief.
I see a man taking photos of women in black robes who have a different way of life and religion to the one I was brought up with. I saw this as a happy photo.
Have to say this dress code seems for the most part to be one of choice rather than one of coercion.
I don't like what it represents but if it's their choice, good luck to 'em.
