So, here is a technicality question....
If someone is being "civil" and using nice - nice words, but in fact acting like an ass, can we call them out on it and say "hey, your acting like an ass." ?? It may be a statement of fact and even civil.  Sometimes its necessary to point out the obvious and call people on things (a time and a place for everything.) Not just delete their comment, but explain to them that it or their action was unacceptable 

I guess my ultimate question sort of revolves around the validation and filtering then - Are comments for vetting / voting, shown in the context - in relationship to - the other comments around them, or are they shown by themselves without any context of the situation ?  That can change the view of how a comment is perceived.
