Growing up, liquor in my household was no big deal, if we wanted to have wine or beer with dinner we could by the time we hit our mid to late teens, but we didn’t do it much. It used to be many states allowed an underage person to drink in a restaurant, NY used to for example, but after they raised it to 21 a lot of states got rid of that.
My state is one of 29 that allows underage drinking in private, as long as the parent is aware of it (10 allow it in a restaurant or whatnot with parental consent-them buying it). My son when younger tried wine (few kids like beer), but never really showed much interest in it, in part because neither my wife nor I are big drinkers,a glass of wine with dinner occassionally or a beer with dinner is about the extent of it, occassionally we might have something like a margarita. Once my son hit about 16 or so he occassionally would have wine with dinner with us (still doesn’t like beer), and never seemed to get into the binge drinking thing, nor did we exactly show him that either.
As far as kids associating drinking with socializing, I think a lot of that comes from the parents, not whether they drank underage. Growing up, a lot of the times the kids I saw go nuts with booze in high school were those who faced massive congitive dissonance, where the parents were of the ‘demon rum’ mentality towards alchohol with kids drinking it, but themselves when they entertained or went to parties, shall we say imbibed, it is how kids ‘catch’ the idea of drinking and socializing I suspect. I think that may explain why kids in Germany and other places where you can have beer or wine by your teens, may not be necessarily responsible drinkers, it could be the causality is what they catch at home so to speak and other factors.
The reason the drinking age was pushed back was not because of physiological differences, it was done primarily to keep booze away from teens. When the drinking age was 18, there were plenty of kids in high school who could legally buy booze and were doing so for their buddies, the other reason was that teens 18-21 had a drunk driving rate and accident rate/fatality rate that was much, much higher than 21 and over, so the federal government basically forced states into the 21 drinking age (basically, if a state kept the drinking age at any other age other than 21 or above, they would lose highway funds).
I would not serve underage kids even if I knew their parents were okay with it, unless the parents were there. Not just for legal reasons, but also because my choices for myself and my family are mine, and I think that is something their parents should decide and govern.
My personal take on alcohol is that we have this weird relationship with it, that like most things human tends to bring out the emotional arguments and so forth. We have those to whom drinking is a big deal (sort of roughly analagous to certain part of the gun owner community) and think anyone expressing concerns about alcohol must necessarily be the modern equivalent of Carrie Nation,and try and cite statistics that kids ‘learn to drink responsibly’ and so forth. On the other side, there are people, often for very real reasons (alcholism in the family or personal) who take the opposite pole, that alcohol is something that needs to be stamped out, that it is the enemy and so forth, they will cite study after study ‘proving’ the ills of alcohol (especially with people under 21), to the point I have had people compare it to smoking, which is absolutely off the deep end for any number of reasons (among other things, a kid having a glass of wine with dinner occassionally, or a younger kid have wine mixed with water or seltzer, which is still common in Europe, is not going to hurt them and may be beneficial in some ways, whereas with smoking, forget it).
Like I said above, I think alcohol and underage kids has to be a personal decision. Based on my own experiences with it, based on history to a certain extent, I don’t think there is any harm from kids having wine or beer occassionally (note I am talking irregular, light drinking), and I think things like binge drinking and kids going crazy with booze might be influenced by having access at home, but as a reason to let underage kids drink it is as flimsy as the Carrie nation approach . I think it is much like sex, that there are a lot of taboos around drinking, a lot of things that come out of emtions rather than logic (want an example? My wife went to the liquor store when my son was young, my dad was visiting, and she was buying beer and a couple of other things. My son was about 3 or 4, and while they were in the store my son reached up and was helping push the cart, like kids love to do. The guy who owned the store had a fit, said he could be fined if an inspector happened to be in the store, that the liquor laws were such that a kid couldn’t even be perceived to be involved with alcohol (a lawyer friend of mine, who worked with establishments with liquor licenses, confirmed that, it is the same way that these days if you have kids, they cannot sit at the bar, even if the place has food and the kid obviously is not drinking…which smacks of the ‘demon liquor’, rather than being about protecting kids.
