Genetic determinism?

Belief Corner: Religious and Political Debate - Educated out of God?: "What those genes have given humans is an extremely flexible massively parallel computer that for instance is capable of recognizing friends instantly from a variety of positions and from body language and facial expressions determine their mood and feelings toward us at that moment and then communicating that information almost instantaneously through large fast mono-dendrite nerves to action centers of the brain which use the information to take appropriate action. One might say that the ability to recognize faces and determine moods is genetic and perhaps it is. But appropriate actions in response to that knowledge? Aside from simple paradigms like fight or fly, useful of course but not real useful at a cocktail party or business meeting, the mind has considerable flexibility in determining appropriate behaviors. Unless the genetic imperative is do the right thing, the genetic component in normal social interactions is nil."
