Each side of the triad has had its share of bad press. We have all read about or seen fictional portrayals of birthmothers who abandon children in dumpsters or who come back to stalk and reclaim their relinquished offspring. Likewise there are news stories about potential adoptive parents who knowingly buy black market babies or who fake pregnancy and murder pregnant neighbors to claim their children. The ones most frequently portrayed in a negative light however are adoptees. Although the character's birth records would not have been sealed given her circumstances, the show's writers deemed it appropriate to get a jab in at open records by having a main character make the remark that records should not be opened because of such people.
Adoptees are more aberrant and dangerous than the rest of the population.
Negative stereotyping keeps the public thinking of adoptees as eternal children who should be grateful to have homes at all. Those who go bad demonstrate the danger of diverging from this assigned role. Thanks to such perceptions we often find ourselves apologetically explaining why we would dare to want to know where we came from. It's ok in my case since my adoptive parents support me. They are my real parents.
