This article needs to differentiate between vapid criticism and constructive criticism. Constructive criticism always provides good, meaningful advice for how to fix potential issues, is not unnecessarily harsh, and is willing to work with opposing criticism. People disagreeing about how to fix something can be just as bad as disagreeing on whether its broken in the first place. Constructive criticism is healthy and does not usually destroy anyone's self-worth, unless they simply can't take criticism at all in which case they will never improve.
