Alcohol is alcohol whether it's in beer, wine, or liquor. It has the same effect on the human anatomy no matter where it comes from - it produces stupid behavior. Why is there no out-cry to ban beer and wine comercials? Don't these ads provoke the youngsters to drink as well? I think kids are going to learn more from the actions they see in their own home than from on TV. This of course means that people actually have to act responsibly around their kids.
Alchohol produces stupid behavior (and worse) only when consumed excessively. It can also ruin your liver when consumed excessively. Yet taken in moderation, alchohol (ideally in the form of beer or red wine) actually had proven health benefits such as reduced cholesterol, improved circulation, reduced stress, among other things. That is why it is so important to teach moderation as opposed to abstinence.
To me, those arguing in favor of Prohibition are no better than those arguing for gun control. Proponents of gun control always point towards tragedies involving children to make their case that guns should be taken from everybody. Well here we have prohibitionists using the welfare of children as a tool to take away alcoholic beverages from everybody. It is really contemptible, these tactics.
