We're talking about everybody's free right to have choice. And so what we're also getting are interesting messages like you really need to obey the command of Allah and put a scarf on your head. And what we caution well-intentioned Americans and others to think about is whether the scarf matches their own values related to issues of honor and shame.

What we are saying is we have to be smart about the ideology that is putting this idea into the world that a woman must be defined by her idea of modesty, that she is the vessel for honor in a community. And I believe that we have to be very pragmatic, too, about the consequence of this. Women in Iran and Saudi Arabia are jailed, punished and harassed if they don't cover themselves legally, according to the standard of those countries. So the consequences for many women is oftentimes very dark.

I think that we don't have, here in the Middle East or in Africa, as much threat to our physical and economic livelihood as women in other parts of the world. But the continuum is the same. The pressures on women to fit into a certain image of a good Muslim girl is the same. The controls and rules are the same, but there are different degrees of it. So, in America, a father will threaten a daughter that he will disown her if she marries the American boyfriend and in Pakistan she faces acid thrown on her face. The power dynamic is the same, it just expresses itself differently.

Talk to me 20 years ago and I had a complete sense of illegitimacy as an American Muslim. I felt like I wasn't authentic. But I don't understand and I don't believe or subscribe to this idea that I don't have a right to speak as a Muslim because I'm an American. Being Muslim is to accept and honor the diversity that we have in this world, culturally and physically, because that's what Islam teaches, that we are people of many tribes. I think the American Muslim experience is of a different tribe than the Saudi Muslim world, but that doesn't make us less than anyone else.

What we argue in the piece is that the headscarf has become a political symbol for an ideology of Islam that is exported to the world by the theocracies of the governments of Iran and Saudi Arabia. Just like the Catholic Church in the 17th century did religious propaganda to challenge the Protestant Reformation, these ideologies are trying to define the way Muslims express Islam in the world.

There is a fundamental flaw in interpretations of sharia that say a woman or man should be punished for sex outside of marriage.

When we think about Islamic feminism, it is not just about women's rights. It's about a more progressive and tolerant expression of Islam in the world for all people. Women's rights is one aspect of it, it's not the end-all, but I also think that the women's issue is the strongest entry point that we've got to challenging extremism. You raise a woman's issue and you get the backs of the conservatives up against the wall faster than just about any other issue in our community. It's the fastest path that we've got to making change happen.
