No, it is not normal or appropriate for therapists to take the side of a narcissistic parent or any parent in a biased manner. A fundamental principle in therapy is objectivity and impartiality. Therapists are trained to maintain a neutral stance, free from favoritism, and without taking sides in family dynamics or any other situations.
If a therapist were to take the side of a narcissistic parent, it could be harmful to the therapy process and the well-being of their clients. It might further enable or validate unhealthy behaviors and attitudes, preventing the client from exploring and addressing their concerns and emotions.
In situations involving a narcissistic parent, a skilled therapist should focus on supporting the client, providing a safe space for them to express their feelings, and helping them set boundaries and develop coping strategies. The therapist's primary allegiance is to their client's well-being and mental health, and they should work in the best interest of their client's emotional growth and healing.
If you feel that your therapist is taking the side of a narcissistic parent or showing any bias that hinders your progress in therapy, it is crucial to address your concerns directly with the therapist or consider seeking a second opinion from another qualified mental health professional. Your therapeutic relationship should be built on trust and a sense of safety, and it's important to find a therapist who can provide the support and understanding you need.
