I never said Mandela was wrong to use terrorism and thuggery to achieve his political aims- I am in no position to judge him. What I did try to say is that if you want to remember the man, you need to remember all of the man. If all you care about it the myth, fine, but there is no need to post tributes to the myth on the day of the man's death- the myth is still alive, it is the man that needs to be remembered.
It's also worth remembering the truth about Mandela's accomplishments- rather than eliminating the injustice of tyranny for the black majority by lifting the blacks out of poverty, he reduced inequality by dragging everyone down. Since 1990, South Africa has experienced one of the biggest drops in life expectancy in the history of humanity. Economic development has been nil, and the country has had a series of disastrous tribal presidents, some of whom are HIV deniers that have cost countless lives.
There is nothing "classy" about sweeping Mandela's many human victims under the rug, and there is nothing classy about replacing the truth of post-apartheid South Africa's mixed results with a myth that you find comforting. There are real people living there you know, not just myths. They deserved to be thought of as real people.
