The Toureg women are actually very empowered. They do not veil themselves; the men do. They have a very complex culture, which I have studied after my several visits to the Sahara. As far as moving to France, this is pretty common. The desert life is very simple and beautiful, but, like people anywhere, some want a greater complexity-- to study, to engage the world. Also it is a very hard life with frequent famines. Some who can afford it go back and forth-- live in two worlds. His country undoubtably was once under French rule, and thus French is his second language.
I have traveled in the Sahara, camping for 3 wks at a time, with a Toureg crew & guide. All that he says is true, and as simple and as pure as his description. Absolute silence, and at night a wealth of stars. Clear dry air and no light pollution makes the vastness of the night sky overwhelming. That is part of their environment also.
