Okay, I followed the link to that post, and dude I cannot even finish reading because I don't know if I want to engage with her when I was reading through and I got as far as this:

"I know that Apartheid ended 16 whole years ago in South Africa. But I'm going to go out on a limb here and guess that Hollis Kruger (as subtly named as Remus Lupin) probably has some lingering racial issues that might possibly influence his reaction to a lovely woman flirting with him when she presents as a South African woman of color. But the show didn't even blink. Not even a little."

Because all South Africans are racist, right? It's not like Apartheid ended because people in South Africa were opposed to it, and it's certainly not at all even possibly true that when mixed-race relationships were illegal people had them anyway or anything WHAT THE HELL IS THIS.

Ass. Projecting ass. Guess what, you racist toolbag, not every white South African is a racist, and not every black South African hates white people, and just by the way race relations in South Africa are more complicated than black versus white. "South African woman of colour" is a borderline meaningless phrase that sounds like you're trying to say she's Coloured (a distinct racial group, not a generic racist term for black people) but think that makes you sound racist.
