There actually is alot of discrimination amoung aspies. Often times in society people don't discriminate on a label, they discriminate on our "symptoms". It's enough for them to know we're "different".
For one, groups like Cure Autism Now and The Autism Society, are painting a picture of autism as the rain man, there aren't many alternatives in the mainstream light, they tell people we're a burden and MUST be "cured"...
Now, I'm actually not against a cure, if it's done with the low functioning ones in mind and is made optional. But it's more the attitude that surrounds it than anything.
I got an autism group started for high functioning adults in my area (I've told this story somewhere else on these forums) and at first we agreed to allow the NT group leader to help us get on our feet before we could take off and run our own group... This was fine by me, I had no problems with that, because he had a point. But, once we got running and it was time for them to let us run the show, they pretty much refused on the grounds that we needed a babysitter. We WON our right to run the group on our own.
