Damn times changed for the worse, I left SA in late 80s early 90s, went to a mixed race private school (CBC in Boksburg) some of my best friends were black, I also had some who worked on my dads golf course, one of which was unfortunately stabbed and killed when I was 10 or 11. Not to say I haven't seen my fair share of racism though, some of it was shocking.
It's really bad now, the whole country has slid downhill to the point that anyone who can, is getting out. Daily robberies in broad daylight, hijackings everywhere, murder up, rape up, the country's electricity infrastructure has been left to rot and now the country has frequent rolling blackouts to cope with the strain and lack of power, I can go on and on. It's shockingly bad.
What's most amusing is that all the older black folks are still blaming the white people from many years ago, whilst the younger generation, the ones who never knew apartheid are all "you've run this country for over 25 years, the population of white people is less than 5%, time to own your screwups and stop blaming the past". Of course the gov's corruption is absolutely rife too, they're so blatant about it that they're justifying nice new swimming pools as "fire fighting pools so in the event of a fire the fire fighters don't need to run far to fill their buckets" (!!!).
It'll take a long, long time for the country to get back to its peak, if it ever does.
