Has there been any detailed writing done by someone in the disability community on the MSSNG campaign?
As far as I know, the bulk of the things written about the MSSNG campaign are written about Autism Speaks in general, because the MSSNG campaign was one piece of a larger picture. ASAN posted about it a little here: http://autisticadvocacy.tumblr.com/post/104787330327/we-are-notmssng
And here’s some stuff about Autism Speaks:

And this is a documentary made by an autistic teen on the stigma of autism today, and how pity-based campaigning (a la Autism Speaks) is the primary culprit: https://www.youtube.com/watch?v=R3DwCn6VeZY
