The liberal press has reported on this, but the philosophical significance of the South African “racist” riots, is never detailed, for how could it be since it refutes their entire world view? Still, the bare facts are reported:

“South Africa is facing a backlash after rioters in and around Johannesburg targeted immigrants from other African countries this week, torching their shops and leading to at least 10 deaths. Now, angry citizens and governments across the continent are lashing out at South Africa and its businesses, denouncing what they call “xenophobia.” Africans across the continent once rallied behind South Africans in their struggle to defeat the apartheid government, which was finally replaced in elections held 25 years ago. Now, some Africans find themselves in the unfamiliar position of protesting the actions of the same communities in South Africa that they once stood with in solidarity. “The only time we’ve seen this type of cooperation of African countries in terms of backlash,” said Tunde Leye, a partner at the Nigerian political research firm SBM Intelligence, “was in terms of support of the anti-apartheid movement.” Anti-immigrant sentiment is a longstanding issue in South Africa, where the legacies of colonialism and apartheid run deep, and a political shift has not delivered meaningful change to many poor South Africans. Immigrants from countries like Nigeria, Mozambique, Somalia and Zimbabwe are often regarded by South Africans as competitors for jobs and social services. In South Africa, attacks on foreigners have become common, and they surged beginning Sunday when rioters stormed neighborhoods in and around Johannesburg, lighting fires and breaking into shops.”

     While the liberals would like to continue to blame the legacy of apartheid, most of the people doing the rioting and killing were not even alive during that era. To do so as well denies agency to these people, which is “racist.” So, yes, this is an example of Blacks revolting against mass immigration, showing that the narrative developed by the Left that only white super-racists oppose being swamped by migrants, is just plain false.
