It depends on who's talking. One Afrikaaner proudly calls himself a European (I foget his name but he' very renowned in arts and writing), while the other a certain unmistakable FWdK calls himself African. Sadly like millions he speaks no languages of African origin.
In the Springboks we have Africans, Coloureds and European-Africans. Hopefully sometime soon we'll have an Indian as well. But you should spare a thought at how stupid we Africans(Blacks) sound when we tell our children, grandchildren, nieces&nephews that white people are Africans. It's very hard. Out of "politeness" towards you we do, but it doesn't come naturally.
At the end of the day, we should not cloud things by arguments of convenience. Americans call themselves Americans and relegate proper Americans to "Native Americans". In the world there are Africans, African-Americans and African-Europeans etc. I don't see why there shouldn't be European-Africans, but to do that would be to compel so called Americans to accept that they are in fact European-Americans as well and should address themselves as such as they expect of African-Americas&Latin-Americans, but unfortunately those who control the media&publishers would never allow that, and understandably so.
This guy argues very well why he considers himself African, and I'm sure you share his viewpoints.

But this guy also argues very well why we are not all and will never all be Africans.

The reality is certain things will always be cosmetic, "forced" on people rather than accepted and will never hold in everyday life. So don't be quick to raise an alarm if I use the term African. Naturally I'm right. Everyone in the world knows what I'm referring to. It's not meant as a slight to anyone. Think "Happy Holidays' - "Merry Christmas" speak. Remember Walter's take on that?
