Sex trafficking
There are a number of misconceptions about sex trafficking. Sex trafficking and human trafficking are not to be confused with human smuggling. Human trafficking for sexual or other labor may involve transporting victims across international borders, but to meet the definition of trafficking, there needs only to be exploitation of an individual after they have been coerced or deceived, so it does not necessarily involve transportation across national borders. Human trafficking and sex trafficking are often used as synonyms. However, trafficking for non-sexual exploitation may be even more prevalent than trafficking for sexual exploitation, though accurate estimates of trafficking rates are extremely difficult to obtain. Sex trafficking tends to receive more attention from aid organizations and donors due to the greater public outrage that forced sexual labor evokes compared to forced non-sexual labor and thus incidents of sex trafficking are more frequently reported.
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.
