The key points being;
1. the album's infiltration via the promotion by the apartheid regime
2. the result being an actual break down of the barriers set out by the segregational government
3. and, the perception internally by black South Africans, once the album went stratospheric (biggest international album since MJ's Thriller) that the world was listening
I'm not saying Paul Simon meant it. He was almost a-political. Ignored any engagement with either the American or SA governments. I'm saying that, unintentionally, it triggered off multiple key points like a load of mini Franz Ferdinands (not the band).
On to your point; I think folk should be able to say what they want, like Loach, I reckon he's pretty inline with how I'd like to frame my world view in general but, I don't think folk should be greetin', whining kants about this particular subject in this particular way. Henry mentioned false equivalences and I think someone, maybe you, said that about my highlighting the comparison to everyone being upset with folk playing in benjamin netanyahu's Israel but not caring a jot about folk playing in Trump's America. Or even Putin's Russia. In fact, some folk moaned about Russia and their homophobic ways re the Olympics, eh? Nowt about non Russian musicians/DJs as far as I know.
Regarding the conflict looming in the background of this conversation; I detest the collateral damage on both sides and wish a plague on both the aggressors houses. But, and this is a massive but; this hatred of actions persistently conflated to Israel and (whether intentionally or not) Jewish folk in general is utter pish and I reckon someone should change the $#@!in' record and modulate the debate for the better. I'm not saying there's a simple thing that folk aren't getting past the point I made, I'm just saying I think the debate is framed incorrectly and it'd be helpful if folk that are supposed to be pretty intelligent (I'm not meaning you here, I mean Loach, but I'm also not saying your not intelligent!) could spend a bit of time really thinking about their square one.
