Ah, the "Progressive Left"

[gaelic cowboy]

And a silly association it is today. It is well known that lighter shades of hair colour indicate pure Germanic blood, as opposed to the pitch black hair of the Gaels, who are descended from Basques, and in turn Africans, quite removed from the more civilized European races.

That should read pre Gaelic or Celtic basically pre Indo-European there Rhy at least for UK and Ireland it should at the latest early bronze age I would say.
