Chief Justice Mogoeng Mogoeng last night challenged South Africans to confront the issue of race relations, saying it was "tearing us" apart.Delivering the Griffiths and Victoria Mxenge Memorial Lecture at the University of KwaZulu-Natal school of law, Mogoeng said issues of land and economy continued to polarise the country and needed to be addressed and redressed."That land issue ... that economy issue led us to fight each other as South Africans."We have to criticise the government where we need to, and the corporate [world] where we need to, but what is it that we, as individuals, are doing to make this country better?" he said.Mogoeng challenged corrupt and opportunistic tenderpreneurs, saying "we dare not betray" the sacrifices of the Mxenges."Have we resigned ourselves to greed? The course of the struggle was never about a few individuals getting rich, but about the noble ideals of those who sacrificed all for us to enjoy this freedom," he said.The situation called for better understanding of one another and commitment in acknowledging the injustices of the past, as enshrined in the preamble to the constitution ."Griffiths Mxenge could have led a good life and could have resigned himself to amassing much wealth for himself and his family, but he chose to risk his life and he knew what had happened to others, like Bram Fischer and Steve Biko. But nonetheless he dedicated his life to the struggle and paid the ultimate sacrifice," he said...
