Book excerpt: Hate crimes-violence aimed at individuals because they are members of a particular group-were once considered the rare illegal actions of a small but vocal assortment of extremists who thrived on hating minorities. No more. In this new book by two of the country's leading experts on hate crimes, published ten years after their classic book of the same name, these most-recognized authorities and media commentators reinterpret this scourge of our generation-hatred based on race, religion, sexual orientation, ethnicity, gender, and even citizenship. In the aftermath of the worst act of terrorism in this country's history-the bombing of the World Trade Center on September 11, 2001-the authors probe the causes and characteristics of such acts of hatred and, most vitally, their consequences for all of us.
