Johannesburg - The ANC has over-reacted to former president Nelson Mandela's assistant Zelda La Grange's comments on Twitter, the FF Plus said on Monday."The ANC's absolute over-reaction to that which Zelda La Grange had said on Twitter about President Jacob Zuma is indicative of a party which is out of touch with the people of South Africa and the future which they want," FF Plus MP Anton Alberts said in a statement."[ANC secretary general] Gwede Mantashe's obsession to get rid of white domination is an absolute misnomer as whites have for a long time not been governing and the ANC is in control of what the future would look like."Alberts said the debate in this country should be about power-sharing and economic empowerment rather than race."If we are not going to succeed in doing that, the future will unfortunately be one of increasing division."According to Beeld, the ANC called La Grange a "spoilt white person"."She preaches non-racialism to protect white people. Now she's sowing racial division," Mantashe told the Afrikaans daily."Non-racialism is about the total destruction of white domination. So we're fighting against the system and not against white people."La Grange sparked a debate on Twitter on Saturday after saying she felt white people were not welcome in South Africa."If I was a white investor I would more or less leave now. It's very clear from Jacob Zuma whites are not wanted or needed in South Africa," she tweeted."I'm SICK of Jacob Zuma's constant go at whites every few months. Why can't we co-exist without it having to be at the expense of one another."Her tweets were in reaction to Zuma's recent comments that the country's problems began with Jan van Riebeeck, a Dutch administrator who set up a refreshment station in the Cape in 1652.Mantashe said it was a fact that South Africa was colonised by white people."They didn't come here and find the country empty. Racial division is rearing its head again because spoilt white people are driving it." La Grange had since apologised for her tweets.
