"1,738 men in South Africa's Eastern Cape and KwaZulu-Natal provinces."
I don't want to downplay the seriousness of violence in SA, especially against women, but a sample size or less than 2000 in the two poorest and most troubled parts of the country does not accurately reflect the country as a whole.
Rape and violent crime is a huge problem that South Africa has to get to grips with. But, if I recall my basic sociology and history from uni, those areas where there is the most poverty, the least education etc tend also to be the areas where rape is more prevelent.
These figures are so shocking they almost make trying to deal with the problem impossible. It paints a picture where 25% of the 25million men in the country are raping the 25% of the 25 odd million women which is not realistic. What you do have is a country that has serious and systemic social issues that need to be addressed. Those issues vary somewhat from region to region but are real. Making the leap from Zuma's multiple wives to rape in areas of the country most ravished by poverty, aids, and hardship seems a little over enthusiastic to me.
