Recently on a physicians' forum I came across a tragic story about a home birth gone bad. The doctors on the forum were mercilessly critical of the individuals involved, but I couldn't disagree with them. Their tone may have crossed the line from anger over the tragedy into disrespect or even cruelty, but I can't say I blame them entirely - there's a part of every conscientious physician that does get enraged over what's perceived to be preventable catastrophe, and sometimes venting the outrage in private (which this forum was supposed to be), among others who understand, can release some of the tension raised by the story.
