Most people don't acknowledge the disdain for Down syndrome they were raised on. They would never publicly state it. But hidden stereotypes can bubble up when we're less inhibited, for example, when we post anonymous comments on a news story.
They can also surface during times of confusion and fear, which seemed to characterize the deputies' response to Ethan Saylor (he used his second name).
Are deeply-rooted stereotypes that devalue people with Down syndrome also behind the relative silence—in the media and public—over Ethan Saylor's death?
You can sign a petition asking the Obama administration to investigate whether Ethan's civil rights were violated. And this petition calling for an independent investigation.
