Focusing on blame is a bad idea. Not because it's hard to talk about. Nor because it can injure relationships and cause pain and anxiety. Many subjects are hard to discuss and have potentially negative side effects and are nonetheless important to address.
Focusing on blame is a bad idea because it inhibits our ability to learn what's really causing the problem and to do anything meaningful to correct it.
