Maybe another way to approach this would be to do away with certain value-loaded terms and talk instead about how all human behavior is best explained by a complex, partially understood, but limited set of spectrums that will inevitably prove maladaptive to many sets of circumstances in a way that might seem "obvious" to most everyone else. I think there's lots of value in using provocative terms to make that point. If we can accept that everyone really is "stupid, lazy, and insane" I think that should end up robbing those words of their sting. It should prime us to be more compassionate and patient with others and ourselves, not less. I also don't think we can get away from the fundamentally disappointing nature of this without making a totally separate point. It's probably true that any given person is also predisposed to be very well adjusted to many sets of circumstances (i.e. to be kind, brave, and pretty damn clever in their own way etc.), but that's clearly not a guarantee in the same way.
