I'm sure this was thoroughly analysed in a thread entitled "Is Humayan Khan Trump's Turning Point?" in fora devoted to scepticism, so forgive me if I repeat things already said. Khan's speech is a master piece of induced inferences used to get political gain. That doesn't mean that I didn't enjoy him manipulatively bashing Trump by verbal means and malafides, as the Don deserves that and then some just because of the way he has been using his tongue to plough the field of understanding with such tools to the same end.
But anyway, I'm impressed by the use of Khan's induced inferences John Oliver's writers do to add a hilarious induced inference themselves. It's amazing how bad faith minutely rewards in our modern world.
The set of induced inferences I'm talking about is:
Khan: «Donald Trump: You're asking Americans to trust you with their future <non sequitur intended as induced inference #1> Let ME ask you, have you even read the United States' Constitution?[the term "even" intoned for aiming purposes]<non sequitur intended as induced inference #2 -Khan silences the cheers in order to keep the needed momentum> I will gladly lend you my copy! [use of indicative -instead of conditional- and adverb to reinforce the inference]»
Of course, the cheers mean the public fall for the false inferences and those cheers themselves reinforce other people falling for them.
Jocularly, Oliver adds his own hilarious induced inferences supported by adequate gesturing:
Oliver: «<induced inference #3, after Khan's words, consisting in a reinterpretation of the whole paragraph> Ooohh, ****!! That is an American founding document [he slips his hand into his pocket exactly as Khan did...] inspirationally used as a middle finger! [and shows his middle finger]»
What Khan really says: "Trump is a leader, and I will provide him some information if he needed"
What Khan's induces to think he says "Trump is asking too much, as he has clearly no real knowledge of what constitutes the very essence of the United States and how the government works. The same as you, I would like to rub these 'facts' all over his face, given the chance". And Oliver's doubles de bet by inducing "He said '**** you, Trump!' "
There is a whole number of tweaks, pauses, emphasis, careful selection of words and whatnot seeking effect. The most notorious parts of Khan's are about the same and almost everything else in it was just preparing the way to these carefully calculated inferences that damaged Trump hardly.
Well done. Owing to the bovine electorate in front who are merely children with XXL bodies, fire has to be fight with fire, because, you all know, by the cancellative properties of ****, two wrongs make a right, don't they?
