6. Grady MacWhiney

Have not heard that name in years, but recognize it.
Had to refresh my memory, so went to Wiki...

MacWhiney wrote Celtic Thesis," which holds that most Southerners were of Celtic ancestry (as opposed to Anglo-Saxon), and that all groups he declared to be "Celtic" (Scots-Irish, Irish, Scottish, Welsh and Cornish) were descended from warlike herdsmen, in contrast to the peaceful farmers who predominated in England.
They attempted to trace numerous ways in which the Celtic culture shaped social, economic and military behavior.
For example, they demonstrated that livestock raising (especially of cattle and hogs) developed a more individualistic, militant society than tilling the soil.
