Wrong. Conservative very, very, very much want to legalize drugs, drug use, manufacture, licensing, dispensing. Legalization by law is the method.
What you either aren't subtle enough to understand, and probably meant to say was that Conservatives don't want to DElegalize drugs. In other words, Conservatives want large, intrusive, all encompassing government in the drug problem. Just like liberals, just not housing, farm supports, welfare, foreign aid. So from one subject, anyways, Conservatives accept, if not welcome, the principals of big government in general. Big, all encompassing powers, rules, regulations, laws, bureaucracies, agencies, spies, informers, prisons and such.
Many Conservatives have the same fundamental view of drugs, law, and state power as do Leftist with gun control. Just as the leftist ascribe evil powers to inanimate objects and criminalize the possession of those weapons, so do many, but not all, Conservatives with drugs.
I can tell that you disagree with me, but I don't understand your reply.
