Embracing liberalism and its profound sense of equality, especially one that predates society (Lockean liberalism), inherently requires acknowledging that another way of life promoting inequality is bad. This feels contrary to our tolerant nature, but when tolerance for other societies butts heads with our devotion to natural human rights, either we side with the founding fathers in universalizing rights, or we decide that rights have borders. This places liberals (not the party, the modern gov system) in the tension between professed acceptance of other societies and cultures, and in navigating approaches when women are systematically deprived of their rights in other countries, when genocide turns the ground red with blood in Sudan, and when a government orders its people to kill specific political opponents in Russia, Saudi Arabia, Rwanda, North Korea, etc etc. You can't choose both- either you believe in rights as something equally bestowed on every person, or you believe those rights have borders that command tolerating the violation of those rights. Bulliet tries to endorse both, promoting the liberal view while shying away from what he deems bold statements about the world, i.e. refusing to make overarching statements about Islam while implicitly making those statements by deeming specific actions evil, by his recognition of the liberalized 'edge' of Islam as the most promising part of the whole, and by determining that the best solution is participatory democracy and greater freedom of thought. I appreciated his takedown of Lewis, but the tenuous design of his argument (Islam and Christianity appear less like twins and more like two distinct civilizations, so pretty much what I already thought they were) leaves me yet more convinced by Lewis. Bulliet's remarks are most instructional in their critique of how the Middle East has been perceived, especially in chapters 2 and 3, but otherwise lack a strong vision for how the Middle East should be seen, wavering between a tendency for liberalism and a fear of essentialism.
Ultimately, I see his vision (shared by Noah Feldman and Abdullahi An-Naim) of what Islamic civilization could be (see ch 4). Still, Bulliet's insistence that we view everything through a lens of impartiality is negated by any belief in liberal values, which require us to take a particular stance. This review is really only on the sidelines of what his work discusses, but it really irked me that he critiqued Lewis for his westernized view while sharing those same prejudices, only more disguised. We are all marinated in the same values, for better or for worse, and it would do better to embrace them boldly if our end goal is that they are realized for everyone.
