So Derec do you really have some statistics on this? Also, do you have any conflicts of interest in determining a conclusion? I don't. To both JonA and Derec, I did not say anywhere that I 100% support the conclusion. I just wrote what the facts are that break down the typical way libertarians/masculinists/wingers/whatever conceptualize the argument. Indeed it is far more complicated than that. If you're going to make threads about the issue while supporting your stance you're going to have to include such facts and show your work. Just posting "France is a shithole" isn't good enough. I'm not going to sit around playing devil's advocate or tit-for-tat all day either because it's not my onus.
What I disagree with about this law is the overgeneralization of it. While it's certainly true that a certain percentage of prostitutes are sex slaves (might be 90%, might be 10% - I have no idea), another percentage of them have chosen the profession. Arresting somebody who's not raping a sex slave just because there's another person out there who is raping a sex slave is an immoral action.
Additionally, it seems to me that it would continue to make the profession more dangerous for women because it keeps the whole thing as part of the underground economy. With the rise of online escort review boards and the like, if someone posts "I got arrested while visiting Dakota McNasty", that would drive a whole shitload of customers away from her, so it's heavily in her interest to not go to or cooperate with the cops even in situations where she really needs to. Additionally, if a customer sees evidence of coersion or abuse while visiting a prostitute, you want him to be able to report that and not put impediments in the way of his doing so because he's worried about getting a criminal record himself if he talks to the police.
Sex slavery and human trafficking are horrible problems which need to be dealt with. Laws like this, however, seem to me to be inferior to full legalization of the industry in terms of giving authorities the tools required to combat them.
