Dude, harassment and rape are NOT the same THING AND neither one are prostitution!
I never said they were. All I´m saying is that they have specific legislation, and that shows that abuses of that kind are somehow special, otherwise we could just use the general, non-specific harassment or kidnapping laws to prosecute these types of crimes.
Any type of slavery is wrong and sex trade is not the only place you find slaves.
But not all types of slavery all equally wrong, are they? That was my point.
I think you're making the assumption that we should make laws based on what society thinks is acceptable. This might be your problem. If laws were based on what society thinks is acceptable social progress would likely be even slower. Society doesn't think rationally about laws overall. In fact, many things that society has thought in the past would be terrible if they allowed it to influence law. Some of those things would include the killing of homosexuals, slavery being legal, legal indentured servitude, and drinking alcohol being illegal.
In reality, the reference to society is the Bandwagon Fallacy and, quite frankly, it is not worth jumping on.
The reference to societal views was one of two two different angles in which I was trying to show that there is a difference between sexual and other types of abuse. The other was an appeal to individual morality, with the example of the rape of the daughter I have repeated several times.
I know we are taking about prostitution and not rape, but my argument relies on the fact that for most people abuses of the sexual kind (rape, harassment, whatever...) are distinct form other kinds of abuses.
In that sense sex work is not like any other work. Just like cleaning glass windows on a skyscraper is not the same job as cleaning glasses on floor level. One might never have an fall, one might not have fear of heights and do the job happily. But it´s not the same job.
Combine this point with the fact that the market economy sometimes produces abusive cicumstances and inequalities (of course this is what liberalists will never admit since for them the market economy is the ultimate force of good), and you can have a an argument for the illegalisation of prostitution for protectionist reasons.
I see this parallel to the spirit of work safety laws. Let´s take industrial presses for example, a very common type of machine. (
http://en.wikipedia.org/wiki/Hydraulic_press) Not so long ago workers used to work in these machines with no protections, sticking their hands in the thing and missing a limb every so often. Nowadays one is not even ALLOWED near one of these machines unless the machine has a number of protections that make it almost impossible to have an accident (detectors, covers etc.).
Even if a worker says that he´s so confident about the job that he can, and wants to work in an unprotected press,
he´s not allowed to.
In a similar spirit, if sex work is deemed too "risky" or demeaning by society, an outright ban (or very strict regulations and controls) might be enacted. And the fact that some sex workers don´t think the work is dangerous or demeaning does not invalidate this, just like in the case of the press worker.
However I understand your argument, that ultimately everyone has a choice and that some (or many) sex workers do it voluntarily and see it as "any other job", So they have a right to do that kind of work, since they are not hurting anybody, not even themselves. It is a strong argument and I´m even inclined to say you´re right.
But for the reasons given, I don´t think it is like any other job (it changes severely once coercion is brought into the picture, something impossible to avoid completely, just like accidents are impossible to avoid completely in industrial jobs), and the "choice" is not always so freely made. (It would only be so in a country with a good social security...)
So legalisation should come together with a very strict set of regulations and controls to make it hard for abuses to happen.
