Fear of invading cultural supremacy

William Saletan writes at Slate that he has read three of the recent white supremacist killers' "manifestos" and finds that all of them actually indicate fear of the cultural supremacy of the "invaders" that they go on to kill.  

Which is kind of odd - it's a bit like self hatred of their own group leads to rationalisations for attacking the other.    Interesting, as Saletan usually is.   Here are his last paragraphs:

These reflections on the assets of immigrant communities—spiritual strength, cultural strength, economic and educational ambition—have led some white nationalists to recalculate their propaganda. Breivik, for instance, rejected “supremacist arguments” and portrayed white Europeans instead as an oppressed native tribe, like “Aborigines in Australia and Native Americans in the US.” “Rhetoric related to ‘indigenous rights’ is an untapped goldmine,” he wrote. “Playing the victim card is the most potent strategy of our times.” He concluded with this message: “Preserving your tribe, cultural and demographical, is a basic human right and has nothing to do with ‘white supremacy.’ ” 

Tarrant offered a similar pitch, based on the idea of “diversity.” His massacre of Muslims, he argued, “was not an attack on diversity, but an attack in the name of diversity.” How? According to his manifesto, the goal was “to ensure diverse peoples remain diverse, separate, unique, undiluted.” “A rainbow is only beautiful due to its variety of colours,” he wrote. “Mix the colours together and you destroy them all.” 

What’s happening among these extremists, in short, is a shift from white supremacy to white nationalism. That’s no consolation to the hundreds of people they’ve killed or wounded, or to the millions they’ve terrified. But it does undercut a core premise of their ideology. Even racist mass murderers are being forced to admit, in their own manifestos, that whites are losing their economic and cultural dominance based on merit. The dogma of white supremacy is collapsing.
