I'd be ten different kinds of pissed the fuck off if I walked into that situation. However, he did say he was looking for girls who are being abused or pimped out, which is not my case at all, so maybe it's good for them. I really resent the stereotype that all girls who do sex work are abused, trafficked, pimped out, and miserable, and I feel like this might further that stereotype. Using these women's situations for entertainment also strikes me as wrong. So, I don't know, maybe it's positive that he's helping women who need it, but I think there might be much better ways to go about it than exploiting them for ratings.
I don't think the work he is doing is wrong....but a TV show? All that will do is further demonize the world's oldest profession and keep it from getting legalized in the future.
I find it no more or less disgusting and uninteresting than the vast majority of reality shows.
Regarding the comment about it perpetuating stereotypes and impeding legalization, my selfish response is, "Good". I've seen what happens when this is legalized. Prices plummet and screening goes out the window. In my case, those are the only things it would change. Cops are too easy to screen out, so I don't worry much about them, and if someone attacks me now, I can already call the cops and report the crime without fear of being cited. And trafficking still happens in countries where it is legal... so there's that.
