This idea, the problem on the planet is white people, is the standard belief of the Western elite today, taught in the schools, and acted upon by the governments. It's what multiculturalism and immigration are all about. The speaker quoted above is a little nobody who is not a threat to anyone, the overwhelmingly white establishment that is actively guided by this idea IS a threat.
Harvard professor Noel Ignatiev:
do not limit themselves to socially acceptable means of protest, but reject in advance no means of attaining their goal . . .The goal of abolishing the white race is on its face so desirable that some may find it hard to believe that it could incur any opposition other than from committed white supremacists . . . The key to solving the social problems of our age is to abolish the white race. . . Make no mistake about it . . . we intend to keep bashing the dead white males, and the live ones, and the females too, until the social construct known as ‘the white race’ is destroyed--not ‘deconstructed’ but destroyed.
Ignatiev has not suffered for his genocidal views, he hasn't been censured or fired, on the contrary he's been lionized. That reflects on the system. Amiri Baraka was selected as New Jersey's Poet Laureate not in spite of a lifetime of virulent hatred of white people, but because of that hatred, because it supports the policies of the ruling elite. He only got in trouble for anti-Jewish remarks, his white-hating racism was not at all controversial, it is, in fact, orthodoxy.
From Human Events:
“In my view,” she once explained, “the only intelligence worth defending is critical, dialectical, skeptical, desimplifying." And yet, in her rage against the West, she displayed no complexity in simplifying the white race as pure evil, concluding that "the truth is that Mozart, Pascal, Boolean algebra, Shakespeare, parliamentary government, baroque churches, Newton, the emancipation of women, Kant, Marx, Balanchine ballets, et al., don't redeem what this particular civilization has wrought upon the world. The white race is the cancer of human history; it is the white race and it alone -- its ideologies and inventions -- which eradicates autonomous civilizations wherever it spreads, which has upset the ecological balance of the planet, which now threatens the very existence of life itself."
Sontag was just one step from calling for the extermination of the white race from the planet.
What else do you do with a "cancer" which "threatens the very existence of life itself?"
