I have cousins in France and they are far more married up to the notion that "when in Rome, or in their case France adopt our way of life" than people are here imo. I understand France fiercely protects their secularism and that includes banning the wearing of religious symbols, but at times that comes across as rather draconian and doesn't bode for a cohesive society. Hijabs are pretty accepted here, most people don't give them a second thought, I certainly don't.
Having said that I don't like to see them on very little girls, I think there should be an element of choice about wearing them. That image was reinforced the other day when I saw the heart breaking picture of a hijab wearing little 9 year old Afghan girl who had been sold as a wife to an old man. Her face continues to haunt me.
