Why is Beck promoting an anti-Semite on the radio?
Earlier today, Glenn Beck was regaling his radio audience  with stories of all the old books he'd received from listeners and offered some particularly effusive praise for one particular volume that he was reading called The Red Network: A 'Who's Who' and Handbook of Radicalism for Patriots , first published in 1934. According to Beck, the book shows that "McCarthy was absolutely right," and he lauded it for exposing the unions as havens for communists.
Unmentioned by Beck was the name of the author of The Red Network, Elizabeth Dilling, a woman known to history primarily for two things: her trial for sedition during World War II, and her rabid anti-Semitism.
Among Dilling's more noteworthy works was a polemic entitled The Jewish Religion: Its Influence Today  (originally titled "The Plot Against Christianity"). As the Anti-Defamation League notes , Dilling wrote in The Jewish Religion that Jews consider non-Jews to be sub-human, and that Jews have a hatred for Christians that is expressed in code in the Talmud. More the point, Dilling specifically blamed Jews for communism, writing: "Marxism, Socialism, or Communism in practice are nothing but state-capitalism and rule by a privileged minority, exercising despotic and total control over a majority having virtually no property or legal rights. As is discussed elsewhere herein, Talmudic Judaism is the progenitor of modem Communism and Marxist collectivism as it is now applied to a billion or more of the world's population. ... Socialism is indeed merely the clover held in front of the cow's nose to get her into the barn under the milking machine. It is a mechanism whereby a 'human' can lead a whole non-human herd into the Jewish controlled barn."
Dilling also pseudonymously wrote The Octopus, published in 1940 and described  by Life magazine in 1942 as "a yellow-covered compilation of anti-Jewish slanders." And it appears that Dilling brought anti-Semitism to bear in all aspects of her life -- Time reported  in April 1942 that her divorce trial turned into something of a sideshow after several fistfights broke out and Dilling tried "to make a little anti-Semitic speech," earning herself a citation for contempt. When her sedition trial fell apart in December 1944, Time noted  that Dilling was, at the time, "touring the Midwest, singing anti-Semitic and anti-rationing songs to America-First rallies."
All this information was obtained with a bare minimum of Googling and archive research. Seems like Glenn Beck should explain why he didn't look a little deeper into Mrs. Dilling's peculiar and abhorrent worldview before promoting her works on the air.
