“Event organizers and open-circle coordinators have, I think, a responsibility to participants to provide a safe and comfortable environment. The Pagan community here in the Pacific Northwest seems to be evolving an ethical standard governing organizers. Althea Whitebirch calls it choice-centered, and I offer my perception of it here as a model and a basis for discussion.”
