Rather than working to eliminate the factors that drive women to sex work (71% of respondents to a previous NUS survey identified as women, 17% as non-binary - but I bet most of those were women...), they are campaigning to allow student sex workers to continue working in the sex trade and to do so using university facilities and premises, including halls of residence
