Some context: John Maynard Keynes, 1st Baron Keynes ( KAYNZ; 5 June 1883 - 21 April 1946), was a British economist whose ideas fundamentally changed the theory and practice of macroeconomics and the economic policies of governments. He built on and greatly refined earlier work on the causes of business cycles, and was one of the most influential economists of the 20th century and the founder of modern macroeconomics theory. His ideas are the basis for the school of thought known as Keynesian economics, and its various offshoots. During the Great Depression of the 1930s, Keynes spearheaded a revolution in economic thinking, challenging the ideas of neoclassical economics that held that free markets would, in the short to medium term, automatically provide full employment, as long as workers were flexible in their wage demands.
Keynes sometimes explained the mass murder that took place during the first years of communist Russia on a racial basis, as part of the "Russian and Jewish nature", rather than as a result of the communist rule. After a trip to Russia, he wrote in his Short View of Russia that there is "beastliness on the Russian and Jewish natures when, as now, they are allied together". He also wrote that "out of the cruelty and stupidity of the Old Russia nothing could ever emerge, but (...) beneath the cruelty and stupidity of the New Russia a speck of the ideal may lie hid", which together with other comments may be construed as anti-Russian and antisemitic. Some critics, including Murray Rothbard, have sought to show that Keynes had sympathy with Nazism, and a number of writers described him as antisemitic. Keynes's private letters contain portraits and descriptions, some of which can be characterized as antisemitic, others as philosemitic. Scholars have suggested that these reflect cliches current at the time that he accepted uncritically, rather than any racism. On several occasions Keynes used his influence to help his Jewish friends, most notably when he successfully lobbied for Ludwig Wittgenstein to be allowed residency in the United Kingdom, explicitly in order to rescue him from being deported to Nazi-occupied Austria. Keynes was a supporter of Zionism, serving on committees supporting the cause. Allegations that he was racist or had totalitarian beliefs have been rejected by Robert Skidelsky and other biographers. Professor Gordon Fletcher wrote that "the suggestion of a link between Keynes and any support of totalitarianism cannot be sustained". Once the aggressive tendencies of the Nazis towards Jews and other minorities had become apparent, Keynes made clear his loathing of Nazism. As a lifelong pacifist he had initially favoured peaceful containment of Nazi Germany, yet he began to advocate a forceful resolution while many conservatives were still arguing for appeasement. After the war started he roundly criticised the Left for losing their nerve to confront Hitler: The intelligentsia of the Left were the loudest in demanding that the Nazi aggression should be resisted at all costs. When it comes to a showdown, scarce four weeks have passed before they remember that they are pacifists and write defeatist letters to your columns, leaving the defence of freedom and civilisation to Colonel Blimp and the Old School Tie, for whom Three Cheers.
What did he think that could have been racist?
A: sought to show that Keynes had sympathy with Nazism, and a number of writers described him as antisemitic.

Some context: Michael Kevin Taylor (born 17 January 1949) is an English musician, best known as a former member of John Mayall's Bluesbreakers (1966-69) and the Rolling Stones (1969-74). He has appeared on some of the Stones' classic albums including Let It Bleed, Sticky Fingers and Exile on Main St..
After Brian Jones was removed from The Rolling Stones in June 1969, John Mayall recommended Taylor to Mick Jagger. Taylor believed he was being called in to be a session musician at his first studio session with the Rolling Stones. An impressed Jagger and Keith Richards invited Taylor back the following day to continue rehearsing and recording with the band. He overdubbed guitar on "Country Honk" and "Live With Me" for the album Let It Bleed, and on the single "Honky Tonk Women" released in the UK on 4 July 1969. Taylor's onstage debut as a Rolling Stone, at the age of 20, was the free concert in Hyde Park, London on 5 July 1969. An estimated quarter of a million people attended for a show that turned into a tribute to Brian Jones, who had died two days before the concert. The Rolling Stones' 1971 release Sticky Fingers included "Sway" and "Moonlight Mile" which Taylor and Jagger had completed in Richards' absence. At the time Jagger stated: "We made [tracks] with just Mick Taylor, which are very good and everyone loves, where Keith wasn't there for whatever reasons ... It's me and [Mick Taylor] playing off each other - another feeling completely, because he's following my vocal lines and then extemporizing on them during the solos." However, Taylor was only credited as co-author of one track, "Ventilator Blues", from the album Exile on Main St. (1972). After the 1973 European tour, Richards's drug problems had worsened and began affecting the ability of the band to function as a whole. Between recording sessions, the band members were living in various countries and during this period Taylor appeared on Herbie Mann's London Underground (1974) and also appeared on Mann's album Reggae (1974).
