Keep it civil, please.
Apart from anything else, it's not an unreasonable thing to ask - why have these women not been directed to a sex work project or even here so they can learn for themselves? They're not babies, and do you really want to feel responsible for them if they're just going to behave recklessly and irresponsibly no matter what you tell them, because it's going to start getting either annoying, unpleasant, dangerous or all of the above very quickly?
