"This news story is a case in point. All the men I know don't want to discuss it, it's private to him, we don't know what happened, yadda yadda"
I was one of the men who posted in regard to this specific case that I didn't regard it as any of my business, because apparently nothing illegal had occurred.
It can be preferable to discuss these issues in general terms, especially when the details of the behaviour are very unclear and had only been "reported" by a notorious scandal rag.
One can disapprove of prostitution in its various forms (and indeed, sexual behaviour in general if one finds it unethical or distasteful) without attacking individuals privately engaging in legal sexual behaviour.
I suspect that one recurring problem in these debates is that of "projection". Let's face it, sex is one of the more primitive aspects of human behaviour, something we have in common with vast numbers of cognitively cruder animals, and that crudity is reflected in the behaviour itself which is unhygienic, aesthetically ugly, often aggressive and quite often seems "disgusting" and "degrading" (to repeat terms frequently used in these threads).
There's a strong tendency to direct one's disgust at one's own sexual feelings onto other people and their behaviour, often with unconvincing justification. It would arguably be defensible if one's position was that sexuality in general is an unfortunate aspect of human nature that we should be striving to overcome through guided evolution (a position which I for one respect), but when it's a matter of quietly condoning one's own dirtiness while fuming at the dirtiness of others, it's time to step back and engage in more reasoning, less emotion.
