Someone on another thread said that children are harmed unless their feelings are validated. I disagreed. They said acknowledgement is part of validating.
Let me propose another scenario: A man genuinely feels resentful that his wife is "preoccupied" with their newborn baby.
In my view, I can acknowledge that he genuinely feels resentful. I can even acknowledge that there is a harsh adjustment process to becoming parents. I can also refrain from validating that feeling by not inferring that it is understandable, correct, or healthy for him to feel the way he does, while emphasising that the reasons he feels that way require further (likely professional) exploration.
They are distinct things and the reason is important to differentiate this to our children is because instead of learning some feelings are harmful and wrong, they learn that they should just be selective in how they express those feelings.
"No you can't openly obstruct your friend from entering a competition or make it known you don't want her to (but if you can quietly sabotage her efforts because you feel so threatened by her, then that's okay because your feelings are valid)."
Unreasonable - acknowledging is validating or vice versa
Not unreasonable - they are distinct.
