The term was well defined in the OP as the #2 dictionary definition. (2. the act of passing severe judgment; censure; faultfinding) and not any of the 3-6 definitions. Part of intelligent discourse is not going down rabbit trails of irrelevant thought.
These different definitions are not entirely separate and discrete; they overlap all the time, especially in conventional conversation. Which is why I try in the classes I teach to intervene in the uncritical conflation of the individual and personal with the operation of "abstract" critical judgement. Also, I'm not that sure that the entire thread has been devoted to some "dictionary definition #2" from the OP on at all, and even if it started there why could it not grow and deepen with reference to broader and more complex concepts? Especially if they are connected, as I assert: the consequences of a prohibition against criticism (as an ultimately futile act of self-aggrandizement) do not just play out on the level of social faux pas at ward dinners, but, as many junctures in this thread testify, they connect with how one views the necessity, priority and value of human rationality and the relation of the individual to structures of power and authority.
