I agree.
I wouldn't give my kids alcohol just to prove a point or teach them a lesson.
(Just as a side note, my oldest daughter did go to a driving sesson, taught by the state police, where they have a 'drunk car', for lack of a better term. It's a car that's been programmed to behave as if it were being driven by a drunk driver, so that teens understand how drinking and driving will affect them. I wanted my daughter to learn this important lesson in a safe manner, without any alcohol consumption in use.)
