I didn't get that from the interview at all.
O' Reilly is a douche, but he's just playing devil's advocate there and she held her own ground pretty well.
Just like I said, because they only made a passing reference it without directly pointing at it and developing it as the topic: they didn't state one reason for adults to think of sex workers as necessarily, objectively in whatever way, inferior. When it came to kids even Jenna was agreeing with ORLY (equally tacitly) that there IS something wrong with sex work, instead of acknowledging the big hurting truth, namely, that it is society who (that ?

) decides that sex work IS wrong, and THAT influences a child's opinion.
The point of ORLY and in fact most people (see how in this poll, half the people who don't consider it wrong to regularly watch porn say that they believe that there IS something wrong wth porn) is that, if it would be bad in your present, it's just as bad in the past. I agree with Jenna, and in fact most people wil do if the topic was not sex, that the past is one thing and the present is another, even if you don't use "being born again in religion" as a justification for it. But you don't even need to make that difference between past and present to prove there is not anything particularly wrong with being a sex worker.
As a child, you can always, out of your own personaity and without any influence from society, find repulsive what your parents do, even if it is something generally considered "decent", so being a sex worker doesn't endanger your kid any more than any other condition, unless there is that additional element of society stating bluntly that sex as a work is wrong, just because it is. I see it ALL THE TIME with self-professed tolerant people who have no problem in being loose and even dishonest in any other sort of work, but never with that taboo subject of sex outside the holiness of "relashionship", which is nothing but traditional wedlock without any sort of priest involved, and with a more open attitude (but often not even that) to dispose of that "relationship" at any moment.
She held her ground pretty well, granted, but that only means she didn't sink... at least not more than most people consider her to have sunk already, while she didn't say anything that didn't make them feel even more above her, after her failing to produce convincing arguments to them.
