I can't think of a time when prostitution was a "non-event." It has certainly been forbidden in most of America throughout the nation's entire history. (I said forbidden, not non-existent.) If you're concerned about sexual assault, and we all should be, then we need to address that behavior appropriately. (A good start would be giving more than 6 months in jail to an athlete who rapes a woman.) We should not abandon solid principles of morality, we should not abandon the families hurt by prostitution, in an attempt to address sexual assault. To do so devalues the victims of prostitution.
