Umm. Seriously, I do understand frustration that we often define ourselves through tragedy. And if one decides to avoid such pieces I do understand. But I think that it is not as if there is a saturation point. It certainly is not as if we have magically learned the lesson on avoiding genocie: See Serbia, Rwanda, Sudan, etc...We often take for granted (we being people who are well-read, reasonably well-educated, etc...) just how little most people are actually aware of. And I'm saying this as a history professor...
