Prostitution is the oldest "profession" in the land. Maybe it should be legalised so long as the participants get proper health care.
Either way, you won't stop it! Similarly drug use.In some cases linked probably.
Maybe we should at last realise once and for all these things are not going away, so maybe give in and regulate/legalise it.
Might stop some rapist if he can pay for his fun rather than "taking" it.
Either way, something needs to be done I guess. The link between prostitution & drugs (the addictive side) is particularly worrying!
How you address it, I've no idea!
