Health – you are getting defensive but missing the point. The question was about a client – not a professional. When a client is choosing a therapist, should the gender of the therapist be a factor in the decision? I think even The Wolf would agree it should be (no guarantees though). The real question is to what extent?
Whether professionals must generally treat both genders equally, and whether there are specialists who see opposite gender clients, is addressing the question from the wrong perspective.
