The Libertarian advocates do seem to advance the George Soros socialist model of so-called "harm reduction." Furthermore, they also tend to make generous use of the famous liberal cop-out which whines how everything is all society's fault, as if criminals are goaded into doing what they do because of the policies in place. An example of this is the "anal rape camps" reference, as if the presence of laws against drug trafficking somehow forces men to rape others in prison. As with liberals, they all want to minimize and shirk personal responsibility and place the blame upon society for the bad behaviors of others.
"Laws against dope force men to grow it on other people's property, and force them to use guns to protect their crops!" as if they are not in any way culpable or in possession of any freewill. Laws just make them into zombies, apparently. ;-)
That is, of course, a severe distortion of the actual argument.
Incidentally, you yourself pointed out that crossing the border is a misdemeanor, while holding people at gunpoint is a felony. Well, some drug crimes are misdemeanors, while forcible rape is a felony - and the authorities send the misdemeanants to jail with a reasonable expectation of what awaits them.
