Whilst I haven't read the entire article, the first paragraph is actually on-point: apartheid was shit in a lot of respects, but the schools, especially in rural areas, have dramatically declined since 1994, as have most government-run companies (with the exceptions like Eskom being bailed out every year).
You don't have to like the facts, but that's what they are.
"I think we gotta hand it to Apartheid because schools were very slightly less worse" isn't the argument you think it is. It does paint where you stand quite clearly.
Never start a sentence with "I'm no apartheid apologist, but". Nothing good can ever come out of it.
And an encyclopedia can absolutely do that and still present factual information based on actual research and facts.
You know that just because a lady has blue hair or a person has colored skin does NOT mean that they can't be right about something or do good research. Right? You do know it, right?
Because in the end, when you cry about DEI (whatever you believe it to mean), this is the implication that comes with it: that you can't imagine for a second that anyone who doesn't look exactly like you could ever do anything competently. I genuinely wonder if you've ever thought about that for more than half a second after you closed that Charlie Kirk video.
If you do believe it, fair enough. I guess you're allowed to believe it. But at least be honest about it.
