I just had dinner with friend with a Ph.D. in political science, who is 'relaxed about immigration' and never heard of Edward Gibbon, George Brown or Anthony Crosland. He has just left the Liberal Democrats for the Greens.
He's too ignorant of history to make much discussion useful. This is because political science is a fake discipline. Political scientists should study history instead.
He said that to be a global city London needs a non white majority. I said London was the largest and most important city in the world in the 1920s, the centre of the world in fact. I mentioned Tokyo and he said that Tokyo has ceased to be 'a global powerhouse' because it is mono-ethnic. I mentioned Seoul and Beijing. He said he didn't know enough about those those two. I could have mentioned Shanghai, Mumbai and Delhi.
Instead, I mentioned Istanbul, which was multiracial before Turkey was ethnically cleansed. It was news to him that Constantinople had a Christian majority in 1922.
However, my friend said, completely unprompted, that Nigel Farage was the most important British politician since the war. He was right about that.
And I did enjoy telling him the joke about Brown and the lady in a red dress in South America.
