The chain of relevance is broken.
Using my numbered list above (arrow is chain of relevance): 2 -> 1 -> 3 -> 4
If you’re getting tripped up about apartheid and the mine being separated, just combine them.
1+2 -> 3 -> 4
In GPs post, 2 is not relevant to 4 unless you establish 3. Unless GP is trying to make an unfounded claim that “Elon’s current state is associated with the crimes of apartheid” (where associated means having a not insignificant impact on that state), including 1+2 isn’t relevant. It’s irrelevant that it’s an apartheid era mine because it’s irrelevant that it’s a mine. 4 is not associated with 2 by way of 1+3 like, IIUC, GP implied.
