Hey Lilly Kate,
I share your admiration for Rogers' approach to Humanism. I think client-based therapy is essential to maximizing the emotional value of a session. Focusing on a client's needs and emotional signals, allows a client to feel like their emotions hold value to the therapist. "Rogers believed that a therapist needed to display three features to maximize the effectiveness of this particular approach: unconditional positive regard, genuineness, and empathy" (Speilman, 2014, p.14). I agree with your points on how all people deserve to feel heard and seen in their emotions. Allowing a client to express their emotions freely will lead to progress regarding their state of being.
