close Jewish friend Victor Benjamin Neuburg, using antisemitic slurs, and he had mixed opinions about Jewish people as a group. Although he praised their "sublime" poetry and stated that they exhibited "imagination, romance, loyalty, probity and humanity", he also thought that centuries of persecution had led some Jewish people to exhibit "avarice, servility, falseness, cunning and the rest". He was also known to praise various ethnic and cultural groups, for instance he thought that the Chinese people exhibited a "spiritual superiority" to the English, and praised Muslims for exhibiting "manliness, straightforwardness, subtlety, and self-respect". Both critics of Crowley and adherents of Thelema have accused Crowley of sexism. Booth described Crowley as exhibiting a "general misogyny", something the biographer believed arose from Crowley's bad relationship with his mother. Sutin noted that Crowley "largely accepted the notion, implicitly embodied in Victorian sexology, of women as secondary social beings in terms of intellect and sensibility". The scholar of religion Manon Hedenborg White noted that some of Crowley's statements are "undoubtedly misogynist by contemporary standards", but characterized Crowley's attitude toward women as complex and multi-faceted. Crowley's comments on women's role varied dramatically within his written work, even that produced in similar periods. Crowley described women as "moral inferiors" who had to be treated with "firmness, kindness and justice", while also arguing that Thelema was essential to women's emancipation.

Spence and Tobias Churton have suggested that Crowley was a spy for the British secret services and that among other things he joined the Golden Dawn under their command to monitor the activities of Mathers, who was known to be a Carlist. Spence suggested that the conflict between Mathers and the London lodge for the temple was part of an intelligence operation to undermine Mathers' authority. Spence has suggested that the purpose of Crowley's trip to Mexico might have been to explore Mexican oil prospects for British intelligence. Spence has suggested that his trip to China was orchestrated as part of a British intelligence scheme to monitor the region's opium trade. Churton suggested that Crowley had travelled to Moscow on the orders of British intelligence to spy on revolutionary elements in the city. Spence and Sutin both claim that Crowley's pro-German work in the United States was actually a cover for him being a double agent for Britain, citing his hyperbolic articles in The Fatherland to make the German lobby appear
