I don't understand how the question even arises. Therapists are paid, as I see it, to act. If the therapist acts (hugs for example) in a way the client finds useful, then accept it and go on. They are trained to not be real. The whole set up is unnatural (and every therapist I have ever spoken to has even admitted this). Whether the therapist personally cares or hugs or whatever is starting from a false premise.
