Fueling the Western paralysis in dealing with radical Islam is the late 20th century doctrine of multiculturalism.
Multiculturalism is one of those buzzwords that does not mean what it should. The ancient and generic Western study of many cultures is not multiculturalism. Rather, the trendy term promotes non-Western cultures to a status equal with or superior to Western culture largely to fulfill contemporary political agendas.
On college campuses, multiculturalism not so much manifests itself in the worthy interest in Chinese literature, Persian history, or hieroglyphics, but rather has become more a therapeutic exercise of exaggerating Western sins while ignoring non-Western pathologies to attract those who see themselves in some way as not part of the dominant culture.
