And as you've stated you, much like a preschool age girl, are incapable of changing any belief taught to you as a child.If that's how you read it, Makktasia.
The truth is that preschool girls grow to be girls who grow to be women and a lot of the values learned in childhood last for a lifetime.
I think you're confusing the willingness to discuss with pride in what is being discussed.
People may not be able to totally remove something taught and reinforced by culture like that overnight but it can be undone and you can consciously change your actions and beliefs even if there is some subconscious residue.
A better study to cite would be the racial face picture study where people say who are the more trustworthy people etc.
