@Pixiedust I guess all the drums and screaming would at least keep away the hunters.
All this was preceded in the 1960's by "sensitivity sessions". I went to a few, and my impression was that there was an expected outcome, an expected set of "spontaneous" behaviors, an expected kind of self-revelation.(We were all supposed to end up hugging each other, embrace nonviolence, and oppose the Vietnam war!) I have the impression that these later men's activities were similar in that a particular agenda was pre-set. It all strikes me as manipulative, even if benignly so.
