total and uncritical acceptance of a clients thoughts and feelings is called?

"unconditional positive regard".
   
"Unconditional positive regard is a complete acceptance of the client.
The therapist must show deep respect for the patient's worth as a
person and his rights as a free individual?the patient is free to be
himself even if this means that he is regressing, being defensive or
even disliking or rejecting the therapist?the therapist cares deeply
for the patient as a person, but is does not matter to him how the
patient chooses to behave. He genuinely cares for and deeply prizes
the patient for his human potentials, apart from evaluations of his
behaviour or his thoughts. He is willing to share equally the
patient's joys and aspirations or depressions and failures. (Traux &
Carkhuff, 1967)."
