Convince Amnesty to campaign for Autism rights

Hello,
I wanted to start off by saying that Amnesty International is a great human rights nonprofit organization. But, I've noticed that some things are missing from their "Appeals for action" list as seen on their website. I have been looking for at least a month for some form of involvement with Autism or Disability rights with Amnesty but it hasn't popped up yet. I even sent two emails to them. but they never sent anything back telling me that they would talk about it with their groups or not.
So, that's why i come to you. we need to convince Amnesty International that we need all the help we can get in the Autism rights movement. and talking to them is the first step.
