The left’s greatest intellectual error is its conviction that the world can be divided into a binary power struggle in which both sides agree on the nature of the struggle, but disagree on the outcome.
Islam and the left both claim to have “perfect” systems that can create a utopia… after a whole lot of killing. They are aligned with each other, yet unable to understand each other because their worldviews have no room for anything outside their perfect models. Leftists despise fundamentalists and Islamists despise atheists and yet here they are working together while ignoring what the other believes.
The left cannot process the idea that religion transcends politics. At best, leftists see religion as a subset of politics. And since Islam conforms to their political axis, it must be progressive. But to Muslims, politics is a subset of religion. Politics cannot transcend religion because it is an expression of religion.
