Not all voluntary sex workers are victims of trafficking but that doesn't mean they aren't victims. Research consistently shows that a high percentage of prostitutes have suffered significant trauma in life, usually in the form of sexual abuse, and often in the home when they were young. When the lens through which a person looks at love and sexuality becomes that warped that early in life, it's hard for their trajectory to not become skewed.

I'm not saying voluntary sex workers bear no responsibility for their choices, but I do think it's important to understand that the conditions of a person's life sometimes mitigate moral culpability. This is why we human beings shouldn't be in the personal judgment business. Only God really knows.
