I don't think him or anyone claims he's a historian, but what's he said wrong about the clearances?
He is an absolute gem of a man.
See Neil Oliver and diamonds? One and the same.
He has often claimed to be a historian and still does so on his website, though his twitter says he isn’t one.
His friendly Yoon media often present him as being a historian.
His take that the Clearances weren’t in fact clearances but people shipping off for a bit of adventure and derring-do is a bit of an outlier.
If he claims on his website he's one then he must be one IMO.
His twitter now makes clear he is not, after having been called out on it by historians. He must have forgotten to update his website.
