In 1920 Douglas founded a
right-wing, Catholic, and deeply antisemitic weekly magazine called
Plain English, in which he collaborated with
Harold Sherwood Spencer and initially
Thomas William Hodgson Crosland. It claimed to succeed
The Academy, to which Douglas had been a contributing editor.
Plain English ran until the end of 1922. Douglas later admitted that its policy was "strongly anti-Semitic". From August 1920 (issue No 8)
Plain English began publishing a long series of articles called "The Jewish Peril" by
Major-General Count Cherep-Spiridovitch, whose title was taken from the fore-title of
George Shanks's version of a fraudulent work,
The Protocols of the Elders of Zion.
Plain English advertised from issue 20
The Britons' second edition of Shank's version of the
Protocols. Douglas challenged the
Jewish Guardian, published by the
League of British Jews, to take him to court, suggesting they refrained from doing so because they were "well aware of the absolute truth of the allegations which we have made." The magazine suggested in 1921, "We need a
Ku Klux Klan in this country," but a promotion for
Ostara magazine was generally not well received by readers. Other regular targets of the magazine included
David Lloyd George,
Alfred Viscount Northcliffe,
H. G. Wells,
Frank Harris, and
Sinn Féin. In December 1920 the magazine was the first to publish the secret constitution of the
Irish Republican Brotherhood. From 25 December 1920 it began publishing notorious articles alleging that a "powerful individual in the Admiralty" had alerted the Germans at the
Battle of Jutland that the British had broken their code, and that
Winston Churchill had falsified a report in return for a large sum of money from
Ernest Cassel, who thereby profited. In May 1921 Douglas insinuated that
Lord Kitchener had been murdered by Jews. Douglas ceased to be editor after issue 67 in 1921, after a row with Spencer. He then produced a short-lived, almost identical rival called
Plain Speech in 1921 with
Herbert Moore Pim. Its first issue contained a letter from a correspondent in Germany praising "
Herr" (so spelt) and "
The German White Labour Party". In 1920 he adhered to the idea of "the Jewish Peril", but noted, "Christian Charity forbids us to join in wholesale and indiscriminate abuse and vilification of an entire race." In 1921 he declared it was not acceptable to "shift responsibility" onto the Jews. In his 1929
Autobiography he wrote, "I feel now that it is ridiculous to make accusations against the Jews, attributing them qualities and methods which are really much more typically English than Jewish," and then indicated the country had only itself to blame if the Jews came in and trampled on it. The historian
Colin Holmes argued that while "Douglas had been to the forefront of anti-semitism in the early 1920s, he was quite unable to come to terms with the vicious racist anti-semitism in Germany" under the Nazis. Politically Douglas described himself as "a strong Conservative of the 'Diehard' variety". ==Libel actions==
