Dear Themba, you raise a very interesting issue-what it means to be a "proudly South African". Despite the fact that you do not elaborate a lot on that, it is interesting that one is aware of the controversial meaning of that term. I will tell you what I think very briefly.
For me, the term "South African identity" is problematic, because not everybody in this country fully understands or appreciates the vaue of the so-called "South African identity". As anyone can see, some people still live in big nice houses, some people are still left on the streets. In fact, there is no room for all these various populations of South Africa to integrate socially, culturally and even professionally. People tend to close themselves in their small social circle and identify themselves in the context of this small community that they have become part of. Even at Wits one can see a gear degree of disintegration among the students from various backgrounds. I will not go so far as to discuss the reasons for that. I think that everybody knows what they are.
However, if South Africans are looking with optimism at the World Cup in 2010 and they believe that the whole world will see that the "rainbow nation" in fact exists, they need to open to each other and show more willingness to understand the different backgrounds, cultures and ethnicities of South Africa. If not, the whole idea of the so-called "rainbow nation" will be just one utopian idea. Besides, anybody who claims that he (she) is a "proudly South African" needs to speak more than just one language, such as English. As we already know, South Africa has eleven official spoken languages. And how many people speak at least half of those? This is what we should start thinking about.
Please, Themba or anybody else, let me know if you believe that I should elaborate more on that issue!
