I'm South African, and both my parents in the 50s and 60 were antiapartheid activists. So I grew up very aware of racism. When I returned to South Africa in 2015, I thought things might have changed.

I was delighted to see a flourishing middle class. And then it became apparent that virtually all white people were racists - hard racists.

Here are some of the comments that will stick in my mind forever;

Going out with someone I knew to a Chinese restaurant, she turned to and said, "The Chinese are a really ugly people, aren't they? Not a beauty amongst them."

An attorney whom I complimented at the bus stop about the hat he was wearing. A minute after I paid him the compliment, he said, "They make you think it's not your own country."

A man about the fact that Groote Schuur (the hospital where Chris Barnard did the world's first heart transplant., "They make the place bad, but I suppose if they didn't go there, they'd die, and that would be a good thing."

I got out.

That is not so in other countries in Africa - just South Africa.
