While true that Mandela embraced violence he felt that he had no choice at the time. Terrible acts were being committed against his people by the government of South Africa. I think most telling was that when he finally overcame and was elected president he did not use that power to trample the former oppressors but instead used his power to heal his country.
Yes terrible acts were committed against blacks by the government of South Africa, except that then the blacks came into power it was the blacks committing those same crimes against blacks and whites. Whites because "they felt they had it coming to them" and blacks for "standing up against the other blacks who wanted to commit the same crimes."
Peh, never mind that the ANC still to this day executes people in the streets, but they were most famous for doing so in their own concentration camps. If you call him a hero. I simply look at him like a terrorist who got what he wanted, and the people continue to condone those same actions he committed. And this isn't first hand experience, but it is from second hand from friends I know both white and black who used to live there and have long since fled.
