Yet more Liberaltarian palaver...the 10th amendment trumps the 9th.
I didn't say a word about any amendment. But since you raise the subject: are you ascribing to me the view that "the 10th amendment trumps the 9th"? If so, you're wrong. Or are you stating your own view? If so, please explain; neither the plain language of those amendments, nor any reading I'm aware of, supports your claim.
Then you need to read more. States have the right to make laws for the society they want to maintain, you're welcome to lobby your fellow citizens to elect representatives to make laws you'd like instead of whining about. Using your silly scenario comparing legal behavior "alcohol use" with illegal behavior "pot use" is sophistic. Why not legalize all drugs and compare alcohol with morphine?
Grow up, get a job and move out of your parent's basement. No wonder Liberaltarians are only the irrelevant 2% of the electorate.
