In communicating the racist and unfriendly attitudes of the leading white ideology towards, for example, discrimination and adjustment, Davis constructs characters, which are continuously under fire and in opposition to the oppressing dominant white society. Admittedly Davis utilises his characters to confront the audience and take them out of their comfort zone, showing them the reality of Aboriginal treatment.
Throughout the Great Depression discrimination and racism were both major issues relating to Aboriginals. Jimmy Munday, one of the more outspoken characters in No Sugar is characterised as the activist and lone Aboriginal voice that is constantly challenging dominant white principles. Jimmy is a character shown to constantly rebel against the prejudiced attitude towards Aboriginals. When the officials plan to relocate the Government Well Aboriginals, it reveals the racism in white authority, as the town wants to be devoid of all things Aboriginal, for the sole purpose of a politician winning an election. Realising he is relatively powerless against the oppressing white society Jimmy continues to treat the white authority with hatred, voicing the discrimination he feels: "You reckon blackfellas are bloody mugs. Whole town knows why we're goin. Coz Wetjalas in this town don't want us' ere, don't want our kids at the school, with their kids, and old Jimmy Mitchell's tight' coz they reckon Bert Awke's gonna give him a hidin' in the election."
