You get two types of people here, one group is liberal and support alomost anything against racism, women abuse, welfare reform, you name it, if it promotes freedom they are for it.These are called the Democrats. On the other side of it the people who love racism but deny it exists, they donated to george zimmerman, they hold onto their guns at all cost, believe all minorites are on welfare etc. These are the Republicans. A lot of people who are posting negative things come from this group and they are no different than Apartheid type whites, they even be worst, but this style of thinking has been passed down from their parents and they will pass it down to their kids, thats life. Don't let their lack of evolution sway your understanding of what Mandela stood for as most of them have not taken the time to educate themselves, but just read snippets and focus on something slighlty negative.
If Mandela had ceated a civil war, this country would not have been blessed with "Elon Musk", "Emmanue Dherman" and people Like "Roelof Botha" would not be living the cozy VC life even though his family were high ranking members in the apartheid government.
