Brotherly Love

And Chesterton worshipped his brother Cecil, too, and with Cecil antisemitism was paramount:

In response to this episode, “the Beilis Affair,” Cecil Chesterton characterised Russian pogroms as something horrible, but also something to be understood as part of an ongoing “bitter historic quarrel” between Israel Zangwill’speople (i.e. “the Jews”) and the people of Russia. The “evidence of the pogroms”, he argued, points to a “savage religious and racial quarrel.” He suggested that it was sometimes “a naturally kindly people like the Russians [who] are led to perpetrate the atrocities,” and sometimes it was the “equally embittered” Jews, who, “when they got a chance of retaliating, would be equally savage.” Referring to the Beilis Affair, Cecil endorsed the blood libel, stating that: “An impartial observer, unconnected with either nation, may reasonably inquire why, if we are asked to believe Russians do abominable things to Jewish children, we should at the same time be asked to regard it as incredible … that Jews do abominable things to Russian children – at Kieff, for instance.” Israel Zangwill, a prominent Anglo-Jewish author and playwright, countered Cecil Chesterton’s accusation, noting that following his logic, we should have to accept that if hooligans throttle Quakers then Quakers must also be throttling hooligans. Zangwill also rightly pointed out that it was implausible that a Jew would murder a Christian child for ritual purposes considering no such ritual exists in Judaism. In response, Cecil Chesterton stated that “as to ‘ritual murder’, Mr. Zangwill, of course, knows that no sane man has ever suggested that it [ritual murder] was a ‘rite’ of the Jewish Church any more than pogroms are rites of the Greek Orthodox Church.” He then proceeded to clarify that what he and others had suggested, is that “there may be ferocious secret societies among the Russian Jews,” and that “as so often happens with persecuted sects, such societies may sanctify very horrible revenges with a religious ritual.” In other words, Cecil Chesterton accepted that responsible Jews did not go around committing ritual murder, but did suggest that a sect of fanatical and vengeful Jews did go around murdering Christian children following a “religious ritual”. Eleven years later, his brother, G. K. Chesterton, similarly suggested as part of his complex multifaceted construction of “the Jew,” that “ritual murder” had occasionally been committed by Jews, not by responsible practitioners of Judaism as such, but by “individual and irresponsible diabolists who did happen to be Jews”. Cecil Chesterton, “Israel and ‘The Melting Pot,’” New Witness, 5 March 1914, 566-567; Cecil Chesterton, “A Letter from Mr. Zangwill,” New Witness, 12 March 1914, 593-594; G.

Doesn't clarify the  "innocent innocent" stuff, but shows where the sub-sect stuff comes from.
