A recent New York Times piece asks the question: does alcohol play too big a part in the Harry Potter books and movies?

At issue are a few scenes from the recent movie, Harry Potter and the Half Blood Prince, in which young wizards throw back a few butterbeers and Hagrid, mourning a dead pet, gets so soused he passes out.
From the piece:
In one scene, Harry, Ron and Hermione order butterbeers at the pub, and Hermione ends up with a frothy mustache. While it’s never been entirely clear whether butterbeer is alcoholic, it seems to have an effect on the normally uptight Hermione, who acts tipsy walking home as she throws her arms around the boys.
As the mother of a 10-year-old Harry Potter fan, I was taken aback by the reaction of the young people in the theater. They snickered at Hermione’s goofy grin and, later, guffawed when an inebriated Hagrid passed out. While I don’t think my daughter fully understood what was going on, I wondered how other parents, educators and addiction experts would react.
Liz Perle, a mother of two teenage boys and the editor in chief of Common Sense Media, which reviews books, movies and Web content aimed at children, said she was bothered by so many scenes showing alcohol as a coping mechanism.
“Hermione is such a tightly wound young lady, but she’s liberated by some butterbeer,” she said. “The message is that it gives you liquid courage to put your arms around the guy you really like but are afraid to.”
Sounds a bit like Harry Potter and the Halfwit Parents to me. But then, I don't have any kids. Maybe once you do, you're prone to see danger in even the most innocent of children's entertainment.
It's not that I don't see that alcohol is used for humor (and occasionally as a plot point) throughout the Harry Potter series. It's just that it occurs to me that this could be a good opening for parents to talk to their kids about alcohol and impart their family's values rather than worrying that seeing Harry sip a butterbeer is going to warp their kids' minds and doom their livers.
What do you guys think?
