Let me get this straight... conservatives oppose welfare partly because they don't want the government to protect people from the consequences of their actions (in this case, refusing to work). For this reason they don't want welfare to be available as a way of life for these people. But these same conservatives think government should protect people from the consequences of other actions (in this case, using drugs). For this reason they don't want drugs to be legal. Does this make sense?
Making them legal would take half the fun out of them.
The Robert Hansons of the world wouldn't have had any fun at all in Sodom.
In your mind, probably not anymore than your comparing laziness to ingesting psychoactive substances of uncontrolled origin does to me. Peace.
