It is impossible for me to imagine anyone around who has not come across the terms segregation, racism, black vs. white, etc.; did not have daily encounters with news on these topics; does not have definitive personal opinions about the causes, merits, dangers, etc. related to those. So, it was a very different and interesting experience for me to watch a recent TED presentation video.
I believe watching this video will likely change how one thinks about these social issues. You can watch this presentation using the link below. Your time will be well spent; the speaker has humor and articulates well.
