I will note that, as the article points out, absolutely nobody is saying that it is OK to force anyone to be a prostitute. In addition, I don't think anyone is saying that child prostitution is acceptable (a child cannot properly consent), and so I'll simply ignore that issue as well. Assume we're talking about consenting adults here.
Well... that assumption really ends the debate, at least for me. Your issue, it seems, is not that prostitution is wrong (It is, but that isn't the issue, there are all kinds of immoral sexual acts that should nonetheless not be regulated by the government.) Your issue is that people who are in the prostitution trade are actually being victimized in other ways (raped, assaulted, etc.) But... nobody thinks those things should be illegal.
Let me make my stance clear:
If there is mutual consent between consenting adults to engage in "icky" or bizarre sexual acts for money, then it is what it is. If its consensual, even if its awful, its not my business.
However, if the woman is forced into the actions in any way, its no longer "prostitution", its rape, and rape should never be tolerated.
Going to utilitarianism for a second (this isn't really my reason for wanting to legalize prostitution, but it does counteract some of the horror stories), a prostitute who is legally "allowed" to do what she does is better able to report abuse.
I don't think prostitution should be "accepted." Unrepentant prostitutes shouldn't be allowed to join the church (personally, I'd love to see unrepentant tax collectors not being allowed to join the church as well, but that's another matter.) I wouldn't date a prostitute, and I would be unhappy if any of my relatives decided to do so, or especially one of my future kids. And I definitely don't advise school guidance counselors to present prostitution as a good option. All I'm saying is that it isn't something cops should be arresting people for or stealing their money over. That's it. Peaceful prostitution should be combated without violence and government violence especially. That's it.
