Fifty shades of gay

Artist iO Tillett Wright has photographed 2,000 people who consider themselves somewhere on the LGBTQ spectrum and asked many of them: Can you assign a percentage to how gay or straight you are? Most people, it turns out, consider themselves to exist in the gray areas of sexuality, not 100% gay or straight. Which presents a real problem when it comes to discrimination: Where do you draw the line? (Filmed at TEDxWomen.)
