I know conventional wisdom advises to be assertive with therapists when there's a disagreement. However, I think there should be the caveat that provided there's a history, the relationship had been good, and there's the expectation the talk will go well. It's not the client 's place to train the provider. I think the bottom line is what you hope for from therapy. I'm unsure how important labeling a person is; the important thing is the treatment.
