You are a great comedian. I suggest you give up on acting or at least side track to comedy for a bit because you'll make millions (srs).
What did you hope to achieve with that picture? No shit our eyes are going to be attracted to the only bit of colour on the blank white page, even if it was black. We'd still have looked at it if the dot was any other colour - green, yellow, blue, etc - and even if the background was blue and the dot was red. It's just simple contrast and basic vector lines... it doesn't prove we're racist or anything other than the fact that we wanted to look at the display on the otherwise blank canvas. So if you were looking to make some sort of point (and I assume you were) it'd have to be some deep philosophical bullshit because otherwise you were just linking an irrelevant picture. What does this prove about your "way of being a human being" other than the fact your eyes are attracted to the only thing on an otherwise blank background?
And using "blacks" isn't racist when it isn't being used derogatorily to offend any one. Is "whites" racist in the same discussion? It is even more appropriate when discussing apartheid since... you know... the whole damn thing is based off racial segregation with the intention that different effects land on the different races which are largely separated by skin colour. What do you suggest we use? South African people? That's great for discussing the effects of apartheid. "The South Africans prospered while the South Africans lived in poverty." You need the distinguishing factor to properly elaborate.
