Masondo asked Malema to withdraw his remarks but he refused and left the House.Commenting on the day's events, Mkhize said on Wednesday: "When the issue of gender-based violence were raised, it's almost like my heart sank."She recalled that last year, all parties condemned the atrocity of gender-based violence after Ramaphosa called a special joint sitting to discuss the matter.Referring to Tuesday's events, she added: "Something in me said: 'This is not it.'"'Went too far'She said what was said was not in the interests of the women in question."Now gender-based violence is used to hurt, throw stones and shoot each other."She also referred to Malema's claims about Ramaphosa's late wife, saying: "A woman who had passed on can't speak for herself."Mkhize said since the debate, she wondered what else the female MPs could have done and concluded that they should have walked out.She said since she has been sworn in, gender-based violence "has been our daily struggle" and added that she has often spoken to survivors."The debate had nothing to do with women," she said. "It had nothing to do with stopping the scourge."She said any MP who had information about an abusive relationship had the duty to report it."It was a power struggle for men, fighting over power and control of the House," she said."They went too far."Asked if it was something she would raise in caucus, Mkhize said: "We will stand up.""It is not something to which one can turn a blind eye and not confront.""It undermines our daily struggle. We can't keep quiet.""We are really undermining all the efforts of those in the trenches."Mkhize said they should speak out about the topic and appealed to all South Africans who were able to make a difference - leaders, companies - to tackle gender-based violence.
