I'm not going to get into the issue of Autism Speaks's history of excluding autistic people, its repeated patronization of us, its... well, you get the idea. I'm just going to confine myself to the video.
I will, however, comment that I think this despite the fact that I grew up in the South Florida Jewish community and have read Mein Kampf in its entirety. I am also quite familiar with the Protocols of the Elders of Zion and have seen a translated brochure for Stalin World. During high school, I made something of a study of Soviet propaganda. Keep this in mind when I say that "I Am Autism" is the most offensive thing I've ever seen. It's that bad.
As I've tried to explain before, you cannot separate autism from autistic individuals. Anything said about autism is said about autistic people. Anything said about autism on a demographic level is said about the existence of us as a group; anything said about autism in a child is said about that child.
The following is, other than some changes in number (I changed a few uses of "I" to "we" for gramatical reasons) identical in meaning to the video. Hopefully, it will make just why the autistic community is so outraged a bit more apparent to anyone reading it:
(In sinister tones)
I am the existence of autistic people.
I am visible among your children, but I am invisible to you until it is too late.
I know where you live -- and guess what? I live there, too.
I hover around all of you. I know no color barrier, no religion, no morality, no currency. I speak your language fluently, and with every voice I take away, I acquire yet another language.
I work very quickly. The existence of autistic people works faster than pediatric AIDS, cancer, and diabetes combined.
And, if you're happily married, I will make sure that your marriage fails. Your money will fall into my hands, and I will bankrupt you for my own self-gain.
I don't sleep, so I'll make sure you don't, either.
Having an autistic child will make it virtually impossible for your family to easily attend a temple, a birthday party, a public park, without a struggle, without embarassment, without pain.
You have no cure for me. Your scientists don't have the resources, and autistic people relish their desperation.
Your neighbors are happier to pretend that I don't exist. Of course, until it's their child who's autistic.
We are autistic people. We have no interest in right or wrong. We derive great pleasure out of your loneliness; we will fight to take away your hope. We will plot to rob you of your children and your dreams. We will make sure that every day you wake up, you will cry, wondering "Who will take care of my child after I die?"
And the truth is, we are still winning and you are scared, and you should be.
I am the existence of autistic people. You ignored me. That was a mistake.
And that's the first half. To try and translate the second, I'd need to change the semantics a bit more. Suffice it to say that it's a determined statement that people are getting together to rip their actual child out of the "shell" that we are.
In other words, it's based on the implicit philosophy that we're not real people and that they need to make us into real people.
Edit: Katie Miller did a brilliant parody of the video here. I'm still laughing.
