American Thinker poses a hypothesis, by showing how a definition of Arab culture mirrors PC culture:

Notice what happens if we substitute the word “P.C.” in place of the word “Arab,” and then restate Dr. Kafaji’s psychological diagnosis as shown below. Who among us “irredeemable deplorable Americans” does not feel that this passage aptly describes socially mediated life under Social Justice Warrior P.C. extremism that has only intensified in Obama’s America? “[P.C.] culture is a judgmental culture, and anything a person does is subject to judgment … inducing many fears … with serious consequences on individual lives. Avoiding such judgment can be the constant preoccupation of people, almost as if the entire culture is paralyzed by [P.C. gossip]. In other words, all of the people in [P.C.] society are [meant to be] hostages of each other. [Author’s substitutions]”

There is an analogy there, but it is not the reason leftists crave Islam.

Leftism is a brain program, designed to make the organism survive and reproduce most effectively under conditions of r-selection and resource glut. As r-strategists, leftists are programmed to migrate to areas of free resource availability. In studies migrators have high carriage of the leftism-predisposing gene DRD4 7r.

This psychological design has imbued them with a suite of behavioral drives, from novelty seeking, to migratory urges to travel, to lack of disgust, to a desire to curry favor with out-groups such as the natives where they are migrating to. Also they evolved an urge to turn the out-group against other in-group members, as a competitive strategy to defeat any fellow r-strategists who migrated to the new land in search of free resources with them.

As time went on, and r-strategists found themselves born in lands of essentially limitless wealth, I believe these urges were corrupted. These r-strategists were not about to migrate, but they still had a desire to be surrounded by out-groups, and a desire to turn the out-groups against fellow in-group members. So if the r-strategist does not want to migrate to Mohammed, bring Mohammed to the r-strategist.

Today, in wealthy lands, instead of migrating to the foreign out-groups, r-strategists are programmed to import the foreign out-groups, because they are programmed to want to be around them. To the extent that r-strategists are programmed to desire turning out-groups against fellow in-group members as a competitive strategy, a violent, hostile out-group like Islam just feels like the perfect group to import.

The r-strategy is about reproduction, plain and simple. It doesn’t produce greatness, it lacks loyalty and honor, and at its core it is kind of inhuman by the standards of K-selection. But when resources flow freely, it will swell and bring a return of the harshness that will ultimately re-establish the greatness of the species.

Tell others about r/K Selection Theory, because it explains everything about the leftist mind
