There Needs To Be a Law
Man's inhumanity to man is difficult to stomach; and even more difficult when it is an open secret. Even worse are the animals who could have done something but didn't. (Note Chris Rock's attitude; making a joke of abuse is not helpful.)
We can mistakenly assume that these egregious acts are limited to the upper echelons of Hollywood; but they are not. Workplace bullying is common in two "helping" professions: academia and healthcare. It's no accident that nurses are known to "eat their young."
