Was the beardy bloke in the troll photo Eugene Terreblanche? If so, nice double meaning.
No one seriously says that Mandela was a one-man liberation movement. He was chosen as the focal point for the campaign. Others like Walter Sisulu, Govan Mbeki et al could also have been a focal point, but Mandela had already been named the 'black pimpernel' and had some folk popularity and broader appeal.
On release from prison, he unified the ANC factions, prevented civil war and restricted capital flight. He sought to redistribute wealth in a gradual and work related way. He faced down inkatha who were being egged on by the third force. He became a statesman pretty much overnight, despite coaching when he was in Pollsmoor prison.
Not bad for a guy who had been locked up for nearly thirty years. the task he inherited upon release would have buckled 99 out of 100 people. The man is an example of principled politics whilst being adaptable.
