As an American who regularly spends time in South Africa (I have family from Pretoria) there is a big piece of context that non US residents miss. This is a proxy war against Trump and is 100% political. Rails Girls and Rails Bridge for example has openly discriminated against women (one in particular who is a South African Ex-Pat) over personal political beliefs https://medium.com/code-like-a-girl/a-women-developer-i-know-with-many-years-of-experience-decided-that-she-wanted-to-give-back-to-6857862cee0a#.xxy1tor54 . There is also a large amount of over-reach with sexual assault in the United States at the moment. For example if a man and a women have been drinking, they have consensual sex and then the next day the women changes her mind, she can press charges against the guy and there is little recourse for him. He can face legal action, jail time, loss of reputation etc..
South Africa has it’s problems, and real cases of sexual assault etc. in all countries need to be dealt with, in fact I’ve helped to report them. But IMHO the Americans do not have the solutions.
Back to your original point, the sad reality is that some of the most vulnerable South Africans may end up as collateral damage over this. But most Americans would rather talk about the difficult plight of a privileged American men and women and will launch crowd funding campaigns to pay for their trip to conferences etc. (and quite often easily meet their funding goals) etc.. Yet at the same time they will not even bother with campaigns to help the truly needly people you probably run across every day who live in shacks and may not even have running water, electricity or access to any education. I say this having witnessed all of this first hand.
