While Mark Shuttleworth is originally from South Africa, where bantu people originates, he was not classified as a Bantu by apartheid government. Which is strange because the word Bantu means people. During our dark days of apartheid, as in less than 30 years ago, areas designated for black only were called bantustans.
umuntu, also(muthu, motho) = person bantu, vhathu, batho, etc = people ubuntu, vhuthu, botho, etc = normal behaviour of a human being.
We are still called bantu(people) and ubuntu is our way of life. Ok. Theoretically.
