Rogers held that distress comes from conditions of worth: approval given only when you behave a certain way. Why would conditional approval cause lasting damage?

C. Because the person learns to disown what was never approved

What is never accepted gets edited out, so the presented self and the felt self drift apart, and incongruence, not disapproval, is what Rogers takes to be doing the damage. Unconditional positive regard is not indulgence; it is removing the reason to keep hiding.
