Horses**t!
The 2nd amendment gives every American the right to keep and bear arms. There is nothing in the Constitution that says you have a right to spread STD's across the fruited plains. Grow up you knucklehead!
OK, class, what foolish and dangerous notion is (thinly) hidden in this statement?
I didn't say anything about the Constitution at all, let alone that there was such a right; that's a red herring logical fallacy.
What I said was, your statement that legalized prostitution will lead to the spread of STDs is the equal of statements from the gun grabbers that legalized conceal carry will lead to shootouts and blood in the streets: vivid, emotionally powerful, and empirically wrong based on the observed facts. My comparison has to do with the asserted negative consequences of a policy, not with rights and certainly nothing to do with Constitutional rights. You attempt to whip up fear, which by the way isn't factually founded or justified, in trying to keep prostitution illegal, the same way they would whip up false fears about concealed carry. You, like they, are lying in order to prevent a something from becoming legal.
You might consider using logical fallacies less if you wish to bash libertarians as non-logical debaters. Or, libertarians aside, if you wish to have rational support for your political positions.
