Islam as a polis understands two terms: the Tribe and the Umma. This perspective is fatally limited because it does not give individual Muslims the flexibility or political maturity to make decisions based on enlightened self-interest. When there are only two choices, and those options are at both extremes, then the real choice is simply survival. The notion of individual liberty is not merely anathema; it cannot even be conceptualized under this system.
And since modern liberty is a Western, human, concept, the Islamic community rejects it as inferior to the will of Allah--Sharia law. So, not only can't true Muslims conceptualize liberty, they refuse to adopt it from the West.
