Fair enough. But don't slap it down as a weird or crass idea. The response on twitter to RG - thinking of Nicky Clarke in particular - seemed to have a big and positive impact.
I really don't know what else we have in our armoury, other than getting the message out. I was knackered this evening and m daughter had a play date - her little friend saw my leg and was all 'eurrg! That's horrible!' That was actually quite upsetting, but I didn't tell her to get out and go and educate herself, I let her touch it and ask questions. She still said 'eurrrgg' but I hope I have planted a tiny seed and the next time she meets a physical disabled person she won't be quite so horrified.
And by the way, I don't think she has been 'taught to hate'. It does look weird if you are not used to it.
