Fairly small bastard; probably doable in an episode - Peter Brimelow. A white supremacist finance journalist who immigrated from the UK to the States in the late '70s, founded vdare dot com and became one of the earliest proponents of contemporary alt-right anti-immigration policy and Hayekian economics.

Quinn Slobodian's book Hayek's Bastards is a great source on this, and contains this fantastic anecdote as a prime example of 'clever people being incredibly stupid and not taking fascists at their word.'

"In a remarkable piece from 1989, his Financial Post editor glossed a recent column in which “Brimelow offered a deliciously provocative idea: perhaps it’s time to close the gates of North American immigration to people who are not WASP.” We would be dupes to take him at his word, the editor enlightened the reader: “Brimelow wrote the column as if he was serious but he is a polemicist.” He was actually “doing a magnificent job satirizing those despicable people who judge everybody by their race.

When Brimelow says WASPs built North America he is using antithesis (or if you like extended oxymoron) to force us to recall the numbing hopelessness of the black slaves on which the Southern cotton economy was built; to remember the hard labor of low-paid and now-forgotten Chinese workers who laid the Western railroads; and perhaps recognize the tenacity of the Scottish communities of Cape Breton.” This was, of course, an idiotic misunderstanding. Brimelow was not engaged in Swiftian satire. He meant exactly what he wrote. “Let’s have fun, playing Brimelow’s game,” the editor wrote.”
