Book excerpt: - Why are some kids magnets for bullying? - Why do gay teens commit suicide four times as frequently as "straight" teens? - Why do we have more men and women in prison than any other country in the world? - Why are school shootings and acts of domestic terrorism on the rise? What could possibly be the theme that ties all of these questions together, which provides a window into so many aspects of the darker aspects of human behavior? In a word, shame.
