Whoa, where do you get that alcohol isn't good or safe for anyone?Actually, you can drink in a safer way, but no alcohol is actually good or safe for anyone of any age. It affects young people's bodies more heavily than adults, but that doesn't mean it's safe for anyone.
Repetitive studies show it is good for people, and there's nothing unsafe about moderate alcohol drinking.
Kids're going to mimic adult behavior -- lots of play is copying adult behavior: Playing house, tending baby dolls, cooking, etc. The question is, why would adults allow kids to mimic NEGATIVE adult behavior?
To you, drinking is negative behaviour. That isn't at all a universal. Most people who drink alcohol have no problems with it. Some people have serious problems with it but far more drink wine with dinner or go out for a couple of cocktails or sit at home and chat and have a drink at night and it's not negative and they'd be happy for their kids to have the same relationship with alcohol that they do.
If it's JUST this one thing, likely there's no problem; however, it's rarely a matter of JUST this one thing. Families who promote fake beer for pre-teens are likely also to push overly-adult behaviors in other ways. It'd be interesting to know if this is a pattern within the family.
Again, no one knows this was 'pushed' on anyone, nor does everyone agree that having a drink is overly adult behaviour. Plenty of people, as evidenced by the thread, give their kids wine if everyone is having wine, etc. It's not specifically adult to those families.
I can tell you that within my extended family, we had lots of negative examples and plenty of access to alcohol.
I don't question that this is true for a lot of people, but a lot of people also grow up in families where there aren't negative examples, where people drink socially or with food or whatever and don't ever have a problem and it's treated as nothing more serious than people who choose to drink coffee or not, it's just no big thing.
