Oh people definately should keep an eye on this issue, but other things more subtle like destruction of monuments, eliminating signs in afrikaans, politicizing the game of rugby,etc. have a more demoralizing impact in my estimation. Certain individuals were predicting the near instantaneous collapse of South Africa under black rule (really has less to do with color and more about communism). It has yet to happen so while I understand the motivation to write such a book, I think it does more harm than good.
They change the names, but the Afrikaners AND most blacks still use the old names.
Destroying the monument, which was not only in praise of the Voortrekkers but some blacks too, is demoralizing and Talibanesque.It also WILL hurt what tourism is left.
The book, which none of us has seen, could be okay...we only have this one article talking about it and who knows what bias the author has?
