Oh absolutely.
The real target would be close scrutiny of the things she's saying - giving these the lie would make it harder for anyone else to propagate same. Particularly if associated with venality or shame for the person saying them.
But I agree, not exactly a nuke.
Random thoughts
Need to know what we'd be asking for, not just what we're against. And sell that in context of Austerity.
Would need to research & co-ordinate with what separate disability charities are doing - there may be stuff in the pipeline anyway where we could just swell the numbers.
Mumsnet disability march, appealing to the able-bodied to do the "Be our Voice" thing? But it would be just another ignorable march.
Cyber demo. Also ignorable. Would need a hook to make it "zeitgeist" and appeal more broadly.
High profile legal case against government if any laws being broken - JobCentres already in breach of DDA big time regards accessibility and reasonable adjustments wrt Work-Focussed Interviews. I had my eye on prosecuting but was unable to get the fuckers ever to do anything on paper, even when that itself was a reasonable adjustment. And it turns out that being too ill to work means, oh surprise, I was too ill to work even harder suing people. Plus it costs.
I heard from a friend who works with MPs that when ESA came in about half MPs' caseloads became sorting out the appalling problems. So MPs know things aren't right.
Sorry, that's the contents of my brain rather than a plan of campaign...
