I probably have read more than twenty books on the subject of pre-colonial times basically from the 1400's to the American revolution which of course includes many references to the American Indian and their history. Never in all my reading have I come across a "Native women flawed genetic theory"
Dollars to donuts, it's some off shoot of either multicultural nonsense or a religious spin on why the superior white man was not responsible for killing off the flawed injuns.
