You've got that backwards. In Sweden, buying is illegal, selling is not. Essentially turning the customer into a rapist and the seller into a victim. And rightly so! Considering that most women selling sex are doing so because of human trafficking, or at least coercion or desperation, it's cruel, immoral, and ironic that they are criminalized in the rest of the world outside of Sweden and the other countries that have followed their model.

Men who pay for sex are the driving force behind human trafficking.

Seems to work for them.

Do you know something I don't? From what I hear both sex workers and johns continue to exist, just like in the old abolitionist/prohibitionist model.
