Racism and dogs...

No, Norwegian refugees are colonizing Spain(the elderly) and Thailand(the pedos), not Greece.

Anyway, you could expand your statement to include adopted children, Fisherking. Will an Asian/African/Whatever adopted as a toddler by European parents act according to the culture of its country of origin or the country it grew up in? I can't see any research showing it will act according to the culture of its country of origin, and that sways the facts heavily in favour of nurture over nature.

Nurture will only count for so much. Sooner or later, blood tells.
