Oscar, try attending a Black Monday event next time (in the interest of writing a balanced, accurate account). Maybe then you would see what it was about with your own eyes. Burning flags, really? Hate speech, really? Racist anger, really? Raw grief over the death of loved ones was actually the sentiment of the day. 
The  overwhelming majority of people who participated clearly stated that they were doing it for ALL murder and violence in the country.
I was very encouraged on that day to see the entire staff of our local Spar supermarket (in a busy Cape Town suburb), black and and white, locals and foreigners alike, dressed in black in support of Black Monday. It confirmed my belief, contrary to what was being peddled in the media, that this was a not handful of white people with a racist agenda.
Well done to the journalists who did take time to attend the event, who conveyed an accurate account. Thank You.
