It's my hope and yours too perhaps, that in years to come, (probably when I am long gone) people on the spectrum will take control of their own narrative in a proactive rather than reactive way, and so end a long era of disempowerment and being disempowered. As long as ASD people are regarded as victims or choose that identity themselves, they will be disempowered, because victims are seen by others as people without power, and people without power are "acted upon" rather than self-determining, regarded as "less thans" and "those, them, they".
Though it is certainly a contestable view, I think that the first step in the (slow, too slow) move to pro-activity and taking charge of the dominant discourse is fully understanding the history - inside and out. It's like learning a language: first you have to know a bit of vocabulary, and then you build on that.
It is utterly possible for the ASD community to be politically empowered, though most have to realise that first, before it can begin to happen. The true barriers are not in the hands of outfits like A-Speaks, but in the minds and in the consciousness of the disempowered... well that was a bit of a rant wasn't it? Felt quite therapeutic
