It's not just about keeping up white majority status.
It's about a dream of making whites somehow again the overwhelming majority, others reduced to about 10 % of the whole.
And it's about magically restoring something that is no longer here to be preserved, the Christian clericalist America of the 1940's and '50's, the cultural world of Pat's own youth.
It's about Pat's own identity politics.
But is that the Buchananism of Steve Bannon?
Of Ann Coulter?
Of Milo Yiannopoulos?
At 68, I know perfectly well what it is to remember a very different America.
Forced to choose between the cultural, political worlds of 1957 and 2017, I'll take 2017 without a moment's hesitation.
And his absurd Anglophilia, his weird affection - for an Irish Catholic - for the distinctly English past of the United States, the English culture and racial stock of its colonial beginnings, and the British Empire of Churchill's day, are just bizarre.
Most white Americans are no more English than Pat, and far less sentimental about things English.
And the Catholic Irish?
Pat is like some Algerian child of the banlieues reciting from his French history text some nonsense about "Our ancestors, the Gauls."
He just doesn't know it.
