There are so many good people to honor - I really don't get this. The man and his organization had a history of killing innocent people. For example, Winnie Mandela, who promoted putting a tire doused in gasoline around her opponents heads and lighting it - they called this horrible thing "necklacing."
But, he was a communist, so I guess that makes everything he did okay (protip: communists killed more people than the national socialists (nazis)).

Nelson Mandela was the head of UmKhonto we Sizwe, (MK), the terrorist wing of the ANC and South African Communist Party. At his trial, he had pleaded guilty to 156 acts of public violence including mobilising terrorist bombing campaigns, which planted bombs in public places, including the Johannesburg railway station. Many innocent people, including women and children, were killed by Nelson Mandelas MK terrorists. Here are some highlights
-Church Street West, Pretoria, on the 20 May 1983
-Amanzimtoti Shopping complex KZN, 23 December 1985
-Krugersdorp Magistrates Court, 17 March 1988
-Durban Pick n Pay shopping complex, 1 September 1986
-Pretoria Sterland movie complex 16 April 1988 limpet mine killed ANC terrorist M O Maponya instead
-Johannesburg Magistrates Court, 20 May 1987
-Roodepoort Standard Bank 3 June, 1988
Tellingly, not only did Mandela refuse to renounce violence, Amnesty refused to take his case stating [the] movement recorded that it could not give the name of Prisoner of Conscience to anyone associated with violence, even though as in conventional warfare a degree of restraint may be exercised.
