Survival of the fittest sad to say. Tribal warfare is an ancient behavior. We've evolved to tolerate. We do this by method of shunning. In ancient days, shunning meant a relatively quick death. Survival in the wilds without the safety of the tribe was certainly unpleasant. Today, shunning is death by loss of employment. So that you can't get a toehold to break free from the unpleasantness, death by a thousand cuts. BTW: My comment is just an observation. Although I recognize the behavior, I don't condone it. And, I would hope to be above it. Of course, who am I.
