It amazes me that I am addressing something so basic, but judging from many of the comments to the Juno article, it has to be done.
The problem with what Juno portrays is that it's vintage adoption mythology straight from the "baby scoop era" that's been refashioned for a new generation. If there was any kind of counterpoint in mainstream culture it wouldn't be such a big deal. For most people, Juno just confirms eveything they already thought about relinquishment- that the pain is negligible and most often for the best.
If someone made a movie about teenagers and how smoking is so cool, you can bet they wouldn't be so dismissive of the effects of images in media. Isn't that why it's so controversial to have a beloved character smoke in a tv show or a film? Because the image might influence impressionable minds?
Mythology like Juno perpetuates our silence. As long as we are silent, people will think it's okay to solicit the babies of young, vulnerable women for people they know to adopt.
And they will consider it an insignificant problem, not worth ruining their enjoyment of a funny movie, until their daughter gets pregnant and her doctor, her friend's therapist, and the acquaintances with infertile friends tell her that the best thing for everyone would be to hand over their grandchild to strangers.
