And again you resort to the simplistic 'we do not need government controlling our every move' line. As if I ever suggested any such thing. I'm quite a decentralist, I'm hardly going to advocate for what you keep suggesting.
I provided analysis of why we must use a broader evaluation of those places before we come to any firm conclusions.
Statistics are treacherous things, they need a lot of evaluation and assessment to make sense of them. One can immediately point out large wholes in using these examples. For instance they are quite limited in scope, they are also, in the case of Amsterdam, in a country which is hardly a shining moral beacon for humanity anyway. The conservative should start by considering the social effects; statistics can help, but they are far from a complete guide to such issues. We should look at those involved and the communities in which they take place, but also at their cultural and imaginative setting. Nevada is socially and culturally quite interwoven with the rest of the US, which mitigates the effects of such practices, either way. You also have not attempted to assess the amount of people using these prostitutes, who is using them and the moral effects this has on them, on the prostitutes and on their relations and close associates.
Also prostitution is just a part of a whole cultural and social milieu. Like so called 'gay marriage', we shouldn't suggest that it would end all sexual and social morality, but it would be one more nail in the coffin. The same goes for legalised prostitution in the current. Western contexts.
