If Society accepts prostitution, we will create more prostitutes.
More prostitutes means more disease spread.
Well, the statistics don't prove that out in Nevada.
That's simply not the case where prostitution has been legallized.
I understand why people oppose prostitution due to moral objections (although I disagree, looking at it on a strict cost/benefit analysis to society), but the statement you made is really no different than when the anti-gunners claim that concealed carry laws will have "blook running in the streets," or shoot-outs over road rage. It's just not happening. And where prostitution is legalized, it's a high dollar business, and spreading disease would jeapordize the profits. And that's something that nobody would tolerate.
