People who know me personally know that I describe myself as a "closet Libertarian"....that is, I try not to make it public, LOL. Anyways, the major issue that I find myself disagreeing with many Libertarians on is the drug war. I do not support the legalization of "medicinal" marijuana, and believe that recreational marijuana should also be banned. Furthermore, I think that we should be doing a better job of educating our children about the dangers of drug use, particularly (but not limited to) heroin in my area. There has been a large number of heroin-related deaths and overdoses in the past year or so....kids are throwing their lives away.
Unfortunately, there seems to be quite a few Libertarians who believe that we should just legalize all drugs, and let people alone to take them if they wish. "Live and let live" is a great attitude, but when people start to become dangers to themselves and others, you have a problem.
