It does seem to be bad news week for those from the left.

Look it up youself. You are trying to state that chalk is cheese.

France declared war on Germany and Germany won. The Xhosa, Mandela's group, were every bit as much an invading oppressor as were the Dutch and arrived around the same time. They were not native to SA.
In France the resistance generally attacked the invading oppressor whilst in SA the Xhosa generally killed their own people.

1) There is evidence which suggests that xhosa-speaking people have been there since the 7th century AD.

' Xhosa History. Historical evidence suggests that the Xhosa people have inhabited the Eastern Cape area from as long ago as 1593 and most probably even before that. Some archaeological evidence has been discovered that suggests that Xhosa-speaking people have lived in the area since the 7th century AD.'

2) The French resistance was very active against its own people (it attacked Vichy France's military and ordinary French people they saw as traitors).

So, I'll ask again: what was the difference between Mandela and the French Resistance? 

A nomadic black African. 

Or are you suggesting that black Africans never lived there?

Not at all - I simply wanted a definition. 

So only Black Africans are allowed - no matter what part of Africa they come from..
