to be honest we would have done and said the same exact thing as you. we actually have been in a group like that and our personal experience was disasterous-NOT that it would be like that for you but the others in the group had little to zero ability to control who came out and the triggering of each other was terrible so needless to say that didnt last very long for us. we believe it can be beneficial IF the facilitators have a VERY GOOD grasp on all the members and each one is able to do some sort of self monitoring. sorry if that wasnt too helpful but that was what we experienced ♥
