I understand too, and thought the same thing. And the DM comments are, as usual, beyond contempt.
Am surprised by the lack of understanding here though, actually.
The article said:
A troubled 20-year-old loner with a history of autistic behavior is the monster behind a horrific shooting
He told a friend he believed his mentally disabled brother did it. Adam is believed to be autistic.
A TROUBLED LONER: EMERGING PORTRAIT OF ADAM LANZA
Ryan Lanza's high school classmates always knew something was different about him......It was widely understood that he had mental disabilities - either Asperger syndrome or more severe autism.
All followed by a series of quotes from people who always knew he was a wrong 'un.
At best, the quotes show a total misunderstanding of autism - and at worst, serve to fuel the idea that people with autism should be somehow removed from society, and idea that the DM commenters are all over immediately; of course they are, the article has wound them up and watched them go.
Am surprised some MNers can't see that.
