Prostitution law
However, sex worker activists and organizations distinguish between human trafficking and legitimate sex work, and assert the importance of recognizing that trafficking is not synonymous with sex work. The Sex Workers Alliance Ireland organization explains: "victims of human trafficking may be forced to work in industries such as agriculture, domestic service as well as the sex industry. It is critical to distinguish human trafficking, which is a violation of human rights, from voluntary migration." The Open Society Foundations organization states: "sex work is done by consenting adults, where the act of selling or buying sexual services is not a violation of human rights. In fact, sex workers are natural allies in the fight against trafficking. The UNAIDS Guidance Note on HIV and Sex Work recognizes that sex worker organizations are best positioned to refer people who are victims of trafficking to appropriate services."
Sex workers' rights
Opponents of the sex workers' rights movement, such as Melissa Farley and Janice Raymond, argue that prostitution should be abolished because legalization can increase incidences of human trafficking. The "New UN Trafficking Protocol" by Raymond argues that many victims are trafficked to countries in which sex work is legalized or decriminalized, and because they are trafficked under the guise of migrants they are not protected. Raymond also argues that it is impossible to separate the exploitation experienced by local prostitutes from the exploitative experiences of trafficked prostitutes, as they are very similar. Thus, to end sex slavery, the report declares that everyone involved in sex work needs to be criminalized so that the industry can be abolished. Similarly, Farley argues that engagement in voluntary sex work is a decision made by women in the absence of alternative choices, and that it therefore cannot accurately be described as a voluntary and freely made choice.
