Why Would Anyone Support Islamic Terrorism?

In an article entitled, Why Liberals Support Islamic Terrorism, and Oppose Self-Defense Against It, the Sultan Knish writes:

Liberals routinely reject both individual and national rights in favor of group and class rights. Liberals are also biased against acts of rational self-interest, in favor of emotional expressions of outrage.

Where self-defense is often defined by liberals as a form of entitlement and class privilege. "Grievance based violence" by contrast is treated as a response to intolerable oppression, and an expression of the underclass rising up. Since in the liberal worldview, violence is divided into oppressive and revolutionary violence. Oppressive violence is a function of class privilege, where revolutionary violence is a form of revolutionary justice. So that in the liberal calculus, the middle class homeowner protecting his house from a mob, is practicing "oppressive violence", while the mob is practicing "revolutionary justice".

Understanding this is the most vital part of understanding liberal morality, or lack thereof. Class or group status, defines whether violence is legitimate or not, in the eyes of the liberal.
