Durban - The FW de Klerk Foundation on Tuesday joined the chorus of those condemning the racist remarks of KwaZulu-Natal realtor Penny Sparrow.Sparrow had taken to Facebook and described black beachgoers as "monkeys", in an apparent reaction to litter left after New Year’s celebrations.There has been an angry reaction to her statement across social media platforms, as well as from political quarters.The foundation, in a statement, condemned in the "strongest possible terms" Sparrow’s "deeply insulting" remarks. "Our Constitution calls on us to heal the divisions of the past and to establish a society based on democratic values, social justice and fundamental rights. Non-racialism is one of the foundational values on which our new society has been created. Human dignity is another.""The trouble with Ms Sparrow's remarks is that they reinforce black stereotypes of whites as insensitive and supercilious racists. These stereotypes are also unfair and further erode relationships between our communities," it said. It called on Sparrow to make an unqualified apology for her remarks and "to acquaint herself with the values on which our new society has been established". Economist Chris Hart on Monday also found himself in hot water after he tweeted that 25 years after apartheid had ended, the "victims were increasing, along with a sense of entitlement and hatred for minorities". In response, the United Front issued a statement bashing the economist, who has since been suspended by Standard Bank. "The audacity of white supremacy to assert itself underlines the severe limits and failures of Nelson Mandela’s rainbow nation project." "That the likes of Hart, Penny Sparrow and others unashamedly act out their white supremacy should not be taken as isolated incidents. With the continued failure of the ANC post-apartheid government, white supremacists have become emboldened.""As the United Front, we will play our part in building a society-wide struggle against white supremacy."
