Fair question. I would also add--who could possibly need support more than such a person?

The author (a psychologist) of an xlnt book on harmful therapy ruptures says it's not uncommon for clients to feel a sense of "murderous rage" after a rupture (not to mention grief, shame, hopelessness, betrayal). Given that the client might now be without a therapist, has been left alone with the rage etc, and may well have no other outlet… maybe some of the angry or critical posts here begin to seem entirely reasonable.
