What do you want to know? It addressed a real problem: Alcohol was ruining American life--it still does.
Was it working well?
Of course. The conventional wisdom championed by the Democrat Party over the years was that it wasn't, but outside of a few lawbreakers, it improved things tremendously.
Is prohibition a valid government aim?
Sure. That's why they put it in the Constitution. You know, the document you folks think supports your claim?
After repeal, a great many states continued prohibition, and many counties, especially in the more law-abiding, more religious South, continue that law.
So I would ask YOU: If it is legal for a county in, say, Alabama or Louisiana, to prohibit the sale of alcohol, then why is it NOT legal to have laws against dope?
LOVE to hear you answer that one (if you do, you'll be the first dope-champion I've heard do so).
