You can’t respond to feedback with a counterargument, a justification, an elaboration of the original idea.
Feedback is not a discussion, something you ought to win, a way for you to influence others with your perspective. Feedback is not an attack, something you have to defend against, a way for others to bring you down. In most cases, feedback is also not supposed to start an action, something that puts an obligation onto you, a way for others to have your work rectified or changed.
The only, immediate, acceptable response to receiving feedback is always: thank you!
