Ah, our good friend common sense. Common sense drug laws. Common sense gun laws. Common sense smoking regulations. Common sense food laws are coming soon to a government near you. You are entititled to your own common sense. That, however, does not make it MY common sense, so that is why we have the concept of limited government - to keep you from imposing YOUR common sense on me. Because I'll damn well drink beer tonight when I get home and get a good beer buzz if I damn well please, and if I were inclined to smoke pot, I would do that as well and you could go pound sand. Because your rights to govern me as to my behavior end once I'm on my property. Or they used to, until you and your coherts in the liberal busybody community decided that I was unfit to tend to my own affairs.
