No knock to the group selected as it represents a broad set of experiences but there are some gaps.
A CEO that can help us "unknow" corporate America.
An active or former military who can help us "unknow" war.
A gun advocate who can help us "unknow" gun ownership
A long time retired Jaguar or other to help us "unknow" professional sports
If TEDx is going to help us break down some cultural myths to raise understanding and awareness, then lets cover all of the myths.
I watched an excellent online TED experience in Amsterdam a few years ago and talk about destroying cultural myths...wow! These can be good if the people speaking stick to their strengths.
