"Making a presentation is a moral act as well as an intellectual 
activity.  The use of corrupt manipulations and blatant rhetorical 
ploys in a report or presentation - outright lying, flagwaving, 
personal attacks, setting up phony alternatives, misdirection, 
jargon-mongering, evading key issues, feigning disinterested 
objectivity, willful misunderstanding of other points of view - 
suggests that the quality, relevance, and integrity for evidence, 
consumers of presentations should insist that presenters be held 
intellectually and ethically responsible for what they show and 
tell.  Thus consuming a presentation is also an intellectual and a 
moral activity."
