Honestly, prostitution doesn't bother me, so long as all involved are actually willing. You want to dance near-naked for a horde of strangers, letting them stuff $20s in your G-string? Perfectly legal. Enjoy sex and want to make money off it? FUCK NO, YOU'RE A WHORE AND A DANGER TO EVERYONE, DIEIDIEDIE! Okay, the last one's a bit of a hyperbole, but that's how it comes across, a lot of the time, when it comes to prostitutes. Yeah, a lot of em are, due to circumstances beyond their control, forced into the trade. Then again, some aren't. Legalizing hookers is, to me, just the same as legalizing drugs. You should have a right to put whatever you want into your body, and that includes a cock, and you should also have the right to be paid for a job, even if that job ends with you on your back, counting money, as a guy tosses a rubber into the bin.
The only difference between a porn actress and a hooker is that porn's recorded on tape. In the end, the same thing is still happening: people are being paid to fuck. Turning basic human interaction into financial transactions? That shit happens all the god damned time, and barely anyone bitches. What about live, pornographic webcam shows? Most of the time, you pay for that, and it is human interaction, albeit over the internet. Even on the net, interaction still counts, I don't care what the fuck you say. I'm on this board, I'm a real god damned person, and I'm talking to real bloody people. We, on this board, are interacting, just like we were if we were talking on the phone. The venue and medium change, but the essence of what takes place stays the same.
Is it demeaning, dehumanizing, or an insult to human dignity? That's up to you to decide, and that's an opinion based largely on one's own feelings. The facts don't care what you, or anyone else, feels. Fact of the matter is, legalization and regulation of what are currently dangerous professions would, by and large, remove the danger from said profession. With legal, regulated prostitution, you don't have pimps who can freely beat and/or kill their prostitutes simply because they haven't made enough money. You have enforced protection, in the form of condoms, and you also weed out the workers who make having sex with a hooker dangerous, the ones with STDs or heaven only knows WHAT other forms of hideous disease. It casts away the dross and leaves a refined product, a refined, legitimate trade that makes money both for the companies and their employees, and for the government in the form of taxes.
TL;DR: If you want to fuck for money, you ought to be able to do so legally, with legal protection and sensible regulation to ensure that you neither get infected with STDs, and that you do not infect anyone else, the latter of which is adequate grounds for termination from the trade and revocation of whatever license you may possess, if the infection is incurable. Otherwise, you're simply suspended until such time as you are proven to have been cured of your illness, at which point, you may return to work. Finally, if you want to fuck, and don't care if a relationship precedes it or not, then one ought to be able to go to a bordello, and pay to get your willy wet or your clam roughed up, whichever may be the case.
