Countries with backward laws will eventually phase out in time, as the other countries did. It's a matter of how and when it will happen.
I'm sorry, but that seems like an "easy for you to say" comment. Is that really what you think we should say to the millions upon millions of oppressed women in the Muslim world? Are we supposed to say to those women: "Sucks to be you, but many generations from now, your country's backwards laws will phase out." ?
