"So-called 'radical' feminist groups point to high rates of rape and assault experienced by sex workers as if this were an inevitable, natural consequence of selling sexual services"
It's an inevitable consequences of interacting with men who don't believe women are really human. Men who believe women are human, do not believe that they have the right to stick their cocks in them and use them as wank-socks, just because they've paid for the privilege.
Whenever this topic is discussed, the people who are in favour of the sex trade, never want to discuss the sort of men who are prepared to buy the right to use a woman's body as a masturbatory aid without her enthusiastic participation.
The rape and assault dangers are precisely because of the nature of the clientele - it doesn't matter what legal rights you get, whether the brothels are equipped with clean sheets, whether you get the right to paid holiday and sick pay, the sort of men who feel entitled to buy women's bodies to use as they wish, make them disproportionately more dangerous to women who permit them access to their bodies, than interactions with the average man. They HATE women and they often express their hatred, during encounters with women they have paid to sexually abuse.
No one ever wants to discuss the attitudes of the clients. And how dangerous they are. And how legitimising of those attitudes, support for the sex industry is.
