Should a Therapist tell a patient that they believe drug addicts should be sterilized?

That was very unprofessional. It doesn't matter if you offended her. You shouldn't feel restricted from speaking your mind for fear of offending your psychologist. The psychologist shouldn't go on rants, that's against their job. You need to get another psychologist, I'm afraid. You can never trust or respect her after this unprofessional activity.
