It seems that you interpreted my statement on biology as a statement of
genetic predisposition. While this is also a part, it is not all I meant.
What I did mean was that the recognition of faces -in my opinion- has
nothing to do with the value or appreciation of the face. It is a result of
the way the brain processes faces. Therefore, it cannot be used as a measure
of racism. How the brain comes to handle face-recognition this way, can have
several *biological* causes: predisposition or exposure.
