You're acting as though strong evidence for a cultural component to the gap also constitutes evidence against a genetic component. It doesn't. There's a range of measures of the gap that varies from county to country. You don't know how the gap would measure in a country with a culture perfectly neutral (or perfectly balanced) in all aspects that affect the gap. When you say "it's most definitely NOT genetics" you are taking a leap of faith that is not supported by the data.
