Merlot, no, actually I don't have a rosy vision of prostitution, but I do accept its reality in so far as it pertains to untrafficked, unpimped adult providers. I don't like it when people try to impose their biblical versions of morality on the rest of us. If no one is getting hurt, everyone is an adult, and the actions are consensual, then people should be able to buy, sell, and use whatever they please. Your body, your money, your choice.
Of all the sex ads, what percentage of them do you honestly think are posted by independent providers versus pimps who hawk exploited women and girls? I personally don't know the answer because I've never used Craig's list for this purpose, but I'd guess that most are probably independent adult providers ... or vice officers looking for a collar. Yet the journalist sensationalizes things by playing-up the "helpless underage victims" card in order to outrage viewers. Where was the interview with an independent provider who would probably represent the majority of advertisers? Reports are supposed to be balanced. Hers was not.
Craig provides a service. I'm not going to fault the man for what others do with his product, any more than I would fault a gun manufacturer for producing a rifle that was ultimately used in a homicide. Perhaps Craig didn't have an answer for not purging underage ads because many, if not most of them, are posted by police departments in an attempt to ensnare scumbag pedophiles.
