They're talking about things of which they don't have the slightest understanding, anyway. It's only because of their stupidity that they're able to be so sure of themselves.
I can't decide if this movie is so spectacularly, breathtakingly dumb as to induce stupidity in anyone who watches, or so brutally brilliant that it disarms all reason. What's the difference?
And writers say, as the most forward bud
Is eaten by the canker ere it blow,
Even so by love the young and tender wit
Is turn'd to folly, blasting in the bud,
Losing his verdure even in the prime,
And all the fair effects of future hopes.
One whose troops repeatedly congregate in small groups here and there, whispering together, has lost the masses. One who frequently grants rewards is in deep distress. One who frequently imposes punishments is in great difficulty. One who is at first excessively brutal and then fears the masses is the pinnacle of stupidity.
