At best, your statement is false. At worse, its delusional. I don't know what America you live in, but in the real America of the 21st century, the law of the land is quite clear when it comes to illicit drugs. If you traffic, purchase, possess and/or ingest these harmful and illegal substances and are caught by law enforcement, you will pay the price. Period. Once again, if you choose to oppose America's drug laws in the political arena, thats fine. If you choose to engage in criminal activities related to illegal drugs, thats fine too. But the latter will probably get you locked up in prison and thats fine with me.
You are missing the point. As a conservative, most of the things that you complain about in our current government system are examples of the government ignoring restrictions in the constitution. For example, you argue for gun freedom on both practical (crime reduction) issues and constitutional issues (second amendment). You not only say that you have a need for self defense but that any law that restricts your ability to own or carry guns is a violation of a clear provision of the constitution and is invalid-Don't you?
My point is the same. When congress passes laws in violation of the constitution, those laws are illegal and invalid. Sure, you might get arrested if you assert your rights but you should be able to argue the constitutional point both to the judge AND to the jury. (I hope that if you find yourself on a jury in such a case, you will refuse to enforce unconstititional laws via nullification, no matter whether it is a gun case or a drug case or whatever.)
Libertarians and conservatives should be fighting for Bill of Rights compliance for everyone and everyone's favorite right, guns, drugs, tax issues, business regulation, environmental regulation, all of it. We stand together or we hang seperately.
