The stigma around sex work in the USA exists because prostitution is illegal in majority of places here. It's one of the things that penalizes the employee before the business. In the USA most being exploited or trafficked work in the food production by a long shot, domestic labor comes in second, and sex work and manufacturing come in third. The only reason we don't feel farm hands, factory workers, or maids are just as exploited as sex workers is because they have a legal way to get out once they realize/can act on the fact they are being exploited so there is less concern about them being trapped. Saying you believe in the criminalization of sex work just says you don't want people trapped in the market to have an escape route. Extortion and human trafficking are already illegal, and can be addressed where they occur just like the other professions with high trafficing, but only if we stop throwing the victims of it in jail.

Morally I object to sex for money, but I object more to turning a blind eye to the consequences of laws invented during the end of the 1800 beginning of the 1900 as most were just made to re-enslave minorities, but disguised as "for the good of community/protection"
