I spend a lot of time on a news aggregator site called Fark.com, similar to what I've heard 4Chan is, but not quite the same. Often, they have articles about autism and with each article is a discussion thread. As one would expect there are several kinds of people in every autism thread:
1. The Intellectual/Student/Medical Professional
2. The Autistic/Aspie
3. The Trolls and Aspie Deniers
4. Parents/Family Members
5. The Anti-Vacc
6. The Ignorant
7. The Light-Hearted Joker
1s go there often but say little. 2s defend themselves. 3s aren't worth anyone's time. 4s can get defensive, but most learn a lot from the 1s and 2s. 5s are just nutty. 6s really haven't had much personal experience w/friends or family and they make statements based on popular news opinion. These people are often ones who are pleasantly surprised by what I write. 7s are sometimes hard to identify, but when I realize they mean no harm, I laugh at a good Rain Man reference or two.
I'm both a 2 and a 4. I write a lot there and it is getting noticed. Twice now I've been sponsored for a month's worth of a paid account (Total Fark) for my comments in the autism threads. I figure, it's best to write where my words will do the most good. I could write more here, but most of what I'd say would already be known to the community.
In this way, the only way I know how at this point in my life, I'm doing my best to put out my PSA (of sorts) in these forums hoping one day the message will catch on. I posted a link to Ari's "No Myths" site in my last discussion thread. I hope he got some hits from that.
Someday I'll be able to have a more formal forum to continue my mission of advocacy, but I'm horrible at networking and don't know the first place to start. Until then, I'll just keep on writing.
