I don't support the war on drugs. I realize that we're never going to win it, I'm just settling for a more moderate solution than legalizing everything, as I think ti would be more pragmatic.
When you abandon basic principle in favor of pragmatism as the bedrock for your political views you open the door to an anything goes type of policy. As an atomic libertarian I would not suggest relegalizing every single illegal drug with one stroke of the pen. However once marijuana is legalized the feasibility of leglaizing things like mushrooms and ecstacy can be looked at and then on to cocaine and methamphetamines. Beyond that if we pursue a market solution in which major manufacturers produce these drugs instead of criminals in a basement we can tax its sale, ensure its purity and control its sale to minors.
I'm in the same sphere, but I don't think that government is necessarily evil, nor do I believe that limiting individual actions, in most cases, is also evil. I seek moderation in those issues.
It has nothing to do with evil. I personally have a high threshold of what I would consider evil. What it has to do with is the rights of the individual and self harm is one of those individuals. Otherwise you reduce people to being mere supplicants to an entity with greater ability to use force upon them to make them behave in a manner the stronger entity deems suitable.
The mind is not above manipulation... although the taking of the drugs heroine and meth may be voluntary, the addiction is not. After a while it becomes all consuming. It messes with the brain, and destroys human nature. Am I "anti-liberty" for saying that such drugs should be limited?
Many things can be addictive: alcohol, cigarettes, video games, sex. To limit the ways in which an invidual chooses to alter their mind is to place state ownership over anothers mind. These drugs alter the mind however other things also alter it such as the imparting of knowledge, traumatic experience, and daily routine. A government has no legitimate authority to mandate that certain forms of mind alteration are acceptable but that others are not.
This is a cornerstone of social conservatism in that you desire that the state have the power to regulate personal behavior in order to foster a preconceived social order. There is little difference in curtailing drug usage than curtailing sex habits or censoring ideas.
