The record scratch for me here was the idea that people can choose to be unsure instead of angry.
People hate being unsure. Neurochemistry prefers anger to uncertainty. People get angry about being unsure. We feel anger in large part as our brain's natural salve for the discomfort of uncertainty. The suggestion he's making sort of defines away human nature.
(There's a lot of practical benefit to be gained from understanding this; for instance, skilled consultants put a price tag on certainty; you can sell determinism by itself, separate from any product or service you're more overtly offering.)
