Q39. "Can you think of a time where the 21st amendment ever played some kind of active role in today's modern life?"
A. Of course. It plays a role every single day. If you are a beer drinker, or enjoy wine with dinner, it has an effect in that after the 18th amendment and before the 21st amendment, alcoholic beverages were illegal (de jure, though de facto they were available; this fact contributed to a general sense of lawlessness that helped contribute to the gangsters of the 30s).
