>>10453694Whites are biologically incapable of being born as far South as most Americans live. There's something in the womb and the development process of a fetus where epigenetic factors cause the baby to develop darker hair and eyes in response to the higher UV light experienced in the latitudes that the USA is at.
I've seen this with friends and also my own children. My children are blue eyed and blonde, while I am brown eyed and brown haired. My friend has a son born in Germany who looks like a perfect Aryan specimen, very light blonde hair and bright blue eyes. His son born in the Mid-Atlantic region has brown hair and darker blue eyes.
There's a reason Americans have, over the centuries, become a brown haired and brown eyed race and it isn't purely due to intermixing with non-whites but due to the factors I have cited here.
tl;dr - white people can't be born so far South as America is.
