My singular observation has been that you seem to repeatedly wish to project a view that asks the audience to treat a group with suspicion and doubt. Based on their race and origin.
I think that's spurious, and as it applies to me and just about everybody I know, I know it to be patently false. My first-hand account also seems to be of no value.
A direct parallel would be like me propagating something negative or disparaging about Jews as a whole, due to my feelings about Palestine. I wouldn't do that, and I expect the same courtesy. Group biases are discrimination, and discrimination generally leads to collective punishment. None of these are good things, nor do they make better people of anyone.
It is obvious that not all white South Africans thought alike and that many opposed apartheid to varying degrees. It is also obvious that the vote to repeal apartheid was an enormous step forward. As I’m sure you’re aware, nothing I’ve written contradicts this.
I think trying to bring it back to "white people" when they overwhelmingly voted not to do that is disingenuous.
