Sure, of course we curtail these behaviors. It's uncharitable to read the parent comment as suggesting that we ignore our conscious, moral minds. I understood him as simply saying that the dogmatic belief in humans-as-blank-slates is going to keep being belied by the way humans act in practice, even those who have as much a claim to conscious morality as anyone else. Something as subtle as why you get along with someone and choose to keep seeing them isn't fully-specified, and whenever something isnt fully-specified, our lizard brains have a strong chance to fill in the gap.

In case you think I'm arguing against a strawman, the blank slate view is _extremely_ popular, and likely even more so in the circles that this commentariat likely run in.
