Folks, it can be horribly hard to be on the wrong side of history. In the US, it was slavery and all the horrors that included. Sadly, there were (and quite possibly, still are) some who would still justify that institution. In our case, only a Civil War, hundreds of thousands dead and maimed, and economic catastrophe could finally open the door to a change that would try to help us live up to that original promise that "All men are created equal." We are still working on it, and we still see violence stemming from those differences. But at least our institutions and, hopefully our moral, political, and social commitments are to right previous wrongs and ensure that we ALL have an equal and free stake in our system.
I am no South African. I do, however, know that change can be difficult. The institution of apartheid and all the horrors that included, was their "peculiar institution." (Sorry, an old American reference to slavery). South Africa did have the dubious distinction of being one of the last established political institutions to openly support race-based power structures. And, of course, if you aren't in the "in-crowd", you may as well have been a plantation slave in 1840 Mississippi. I know: There's an argument that the South African system was not slavery. I would suggest, though, that any system that empowers one group over another on the basis of race, ethnicity, or class is a dehumanizing and unjust institution.
There seems to be some notion that the transition of S. Africa from apartheid to a system that provides democratic access for all its citizens was brought on by terrorists. If I understand correctly, the violence in this change occurred on both sides of the issue. You should not, however, choose to hold up the horror of violent action by South African blacks who wanted the freedom, authority, and legal power to live their own lives without looking at the institutional violence directed at those same South African blacks by those in power desperate to maintain a self-serving system.
Change is hard. The power in Apartheid S. Africa was held by a minority of whites that continued to be overwhelmed by the growing black population. When I speak to being on the wrong side of history, the apparent "wrong" here was the travesty of a supposedly democratic government that deprived access by the overwhelmingly largest number of its own people. Sound familiar. We continue to get arguments over this issue in the US. But the transition to a fully democratic S. Africa, while it had its violence, doesn't even register when you consider the horrors of these transitions in the US, Warsaw, Poland in 1940-41, Viet Nam, Cambodia, India, and on, and on.
For me, one of the reasons I particularly admire Nelson Mandela, stems from this: After a life in an Apartheid system that held him as an inferior being; after decades of imprisonment; after a life of trying to bring world attention to the wrongs of Apartheid (and again, I'm not familiar with his terror/non-terror links...); after all of that, this was a man who, elected to form the first non-Apartheid government in S. Africa, promoted a transition that did not blatantly use the institutions of government to violently, economically, or in any other way attack the previous power holders. Based on his actions, I see no strategic attempts to "get even." The fact that he was a man empowered by a majority democratic vote to direct the institutions of a government that spent a long time trying to silence him, I'm also surprised he didn't burn the place down. He didn't. That is the heart and soul of a human being with a large vision for a civil society.
As changes go, I see nothing here as rough as what occurred in the US after the Civil War. The post-war republican Congress was not kind to the formerly rebel states. And the culture of racism bred a reactive violence we still see in the Ku Klux Klan, neo-Nazism, and I'm sure, a host of other racial hate groups. To our credit, these are an un-accepted and minority aberration that is routinely "corrected" by our legal system. But, we killed or boo-ed down the folks who championed a more reasonable transition away from the former confederacy (Lincoln, Andrew Johnson, etc.)
So yes, I admire Nelson Mandela for a number of reasons, but mostly for his post-apartheid willingness to work toward a S. Africa that empowered ALL of its citizens under a democratic form of governance. I also admire his vision for a S. Africa that could hold its head up as part of world community that no longer accepts governments by minorities who hold power at the point of a gun and at the expense of citizens who just don't happen to be of the "correct" skin color, ethnicity, etc. I admire him for being a bigger man than I am: If I lived in those circumstances where I had no political voice, where my white neighbor reaped all benefits of citizenship while I had access to little, where the system systematically treated me differently simply because of my skin color, I'd be a damn sight more violent than anything this man was involved in. So, if that makes me some kind of lily-livered, white liberal, so be it. It is a label I will wear proudly, especially if I can avoid being some kind of supremacist who feels entitled to power, legal authority, economic opportunity, and social status simply on the basis of my gene pool. [Come to think of it, this may well be why southern slave plantations, Nazism, the Klan, and aristocracy are definitely on the outs, historically speaking. Good riddance.]
