Cape Town – The SAHRC is going to investigate the racist insults President Jacob Zuma’s son Edward has directed at former finance minister Pravin Gordhan and former tourism minister Derek Hanekom, Netwerk24 reports.In an open letter, Edward Zuma wrote that Hanekom was a “vile dog trained to maul a black skin”, eNCA reported on Thursday. He described Gordhan as “one of the most corrupt cadres of the ANC who thinks African natives are no better than just being sugar cane cutters who must be forever subservient to a master like him for sustenance”.The SA Human Rights Commission said the content of the letter, especially the statements which encouraged hate on the grounds of race, was offensive, upsetting and a clear violation of the right to freedom of expression contained in the Constitution. The SAHRC said it would investigate “appropriate” actions. On Wednesday evening, Zuma jnr denounced Gordhan and Hanekom as “sell outs.” Both had asked his father to resign. In recent weeks, Gordhan delivered a sharp critique of “corrupt politicians”, a reference to president Zuma.Edward wrote they were “fronts of white monopoly capital and anti-majority rule”. The “sell out Gordhan” wanted blacks relegated to the sidelines, he claimed. “Gordhan and Gandhi views black people as a lower class: K****rs which are subhuman and deserves no status beside that definition.” About Hanekom he wrote: “It was at the ANC's recent 5th National Policy Conference of the ANC that Derek Hanekom, white monopoly capitalist offspring - who is no better than a vile dog trained to maul a black skin, showed us his true colours.” He called him a “minority champion white racist Afrikaner anti-majoritarian sell out” who “vomited on our native black people” during the conference’s economic transformation commission.
