Coleman Hughes gave a thoughtful talk on color blindness at TED, but TED has been reluctant to let its viewers see the talk. Coleman describes the problem at The Free Press. Here's an excerpt:

Like any young writer, I am well aware that an invitation to speak at TED can be a career-changing opportunity. So you can imagine how thrilled I was when I was invited to appear at this year’s annual conference. What I could not have imagined from an organization whose tagline is “ideas worth spreading” is that it would attempt to suppress my own.

As an independent podcaster and author, I count myself among the lucky few who can make a living doing what they truly love to do. Nothing about my experience with TED could change that. The reason this story matters is not because I was treated poorly, but because it helps explain how organizations can be captured by an ideological minority that bends even the people at the very top to its will. In that, the story of TED is the story of so many crucial and once-trustworthy institutions in American life.
