Well, there is nothing in the Constitution that prohibits prostitution. In certain counties in Nevada, it is legal. So other places could do the same if there was the political will. But there isn't. And, let's face it: anyone (man, woman or it) who goes around advocating for legalized prostitution is going to look like a perv, a hooker or a pimp. Of course, we advocate for it on here where we are anonymous; but AMPREV is not the real world.
How many of us would have the guts to do it at work or with our family and friends? Certainly, not me.
