The Autistic Self Advocacy Network (ASAN) is leading a rather impressive campaign in response to Michael Savage's uninformed claims. (If you don't know yet what the fuss is about you can find links to several articles and blog posts about it here.) Several other disability advocate groups have come together to make a joint response to Mr Savage. They have also begun a petition. ASAN has also complied a list of sponsors for Savage's shoe complete with contact information. (One advertiser and a Mississippi radio network have already dropped Savage's show.)
There's a now Facebook group supporting a boycott of Savage as well.
More people, in this case self identified conservatives, are beginning to speak out about Savage's remarks about autism, A Savage Attack: Right-radio wrong. In Alabama state Rep. Cam Ward, R-Alabaster has also spoken up in defense of autistic people and their families. Apparently Ward has been regularly working on improving services for autistic individuals in his state.
