All I could think while reading the first 1/3 of this book is "this is exactly why it is so important that DOMA is overturned." I had never known enough about US school shootings (or how very many there have been in the past 30 years) to know how large a role taunts and insinuations of insufficient masculinity or outright gay bashing -- of boys who weren't gay -- played in eroding the coping abilities of boys who ended up becoming shooters. Eradicating legal discrimination at the federal level won't immediately solve the daily hurdles of hyper-masculine bullying and marginalization so many kids have to face in middle and high school, but it's an important start. What motive does a hyper-masculine high schooler have to lay off the "soft" or "weak" or "skinny" boys when the US government itself enshrines the notion that gay men don't deserve equal status under the law?
The book is not in any sense an apologist for the numerous school shooters. Rather, it is a careful analysis of what conditions we now know have led to young adults believing that mass violence was the only way they could be heard, and armed with such knowledge, we can start to target those underlying conditions. For every shooter, there are dozens more whose suffering is equal but who don't take the final, violent step. For the safety of teachers, students and school employees, as well as for the unsung misery of those who don't lash out, it is important to understand and address the many causes of school violence.
The book is well-researched, with anecdotal data in addition to discussion of studies in the US, Europe, Asia and Oceania. Although I felt the solutions proposed were somewhat over-optimistic, the overwhelming sense of bleakness of the first 2/3 of the book clearly demonstrate that *something* needs to be done. It was not a comfortable book to read, but I thought it was well worth the time invested -- even those of us who fancy ourselves enlightened can use a reminder of how powerful even casual bigotry can be to those who experience it day in and day out.
