To get away with something llike this effectively you would have to use their own WTspeak in a way that didn't set off apostate alarm bells in their delicate little indoctrinated brains. Then say something that on the surface sounds like it belongs to the paragraph but with just a little thinking (cos remember Jduds don't think) it becomes obvious the comment is actually a criticism or posing a - shock horror gasp - critical thinking question.
Then pick up your stuff and calmly walk out while their collective brain first makes the sound of crickets but then one by one pennies start to drop and they start thinking "hang on a minute .."
