When I was in High School, I was part of a group named SOTA – Students Opposed to Apartheid. I learned a lot from seeing movies such as Cry Freedom, talking to teachers and other adults about these things, and reading – a lot. My world view was forever changed. Many, many years later I worked for World Vision, where I had several colleagues from South Africa. Some are still friends.
The world needs more leaders who can really lead like Mandela. RIP.
