In a comment at Sebastian's is repeated the hoary old meme "libertarians just want to get stoned." Rather than snap back with the easy cheap shot of "...and if they did, what business is it of yours, anyway? Who died and made you Commisar?" I will take the time to give a serious answer.
Personally, I don’t care about the dope. Hell, for all I care, you can leave the dope illegal as long you undo all the constitutional damage you’ve done to stamp it out in the last fifty years or so.
All the probulating, door-kicking, snooping and spying, asset forfeiting, and armored personnel carriering has done more damage to this country than a hundred Woodstocks worth of stoners, to say nothing of the obscene profits we have basically legislated into existence for vicious criminal scum south of our borders and in our own cities.
I’d rather my neighbors smoked a bong every day than run the risk of a dyslexic SWAT team taking a battering ram to my front door at oh-dark-thirty. We need to stop burning the village to save it.
