No exploitation here at all. I think this is a commendable organisation with laudable aims, as I said in my OP. However, if you can identify into disability then that means that people like me (able bodied, female, sighted, hearing, no known mental health conditions - just getting a bit old) can exploit this in exactly the same way. And they do - how many of us have seen posters who see having a child in a pushchair allows them to identify into the disabled space on a bus.
I can't identify our of my asthma. Nor can I identify into being disabled.
I was not aware that this language had been used as part of the "disability discourse" but, as that is the case, then surely it is pretty worrying that it has been hijacked.
And, at no point did I mention trans - merely the spreading of the idea of self-id. Clearly, as someone said above, hijacked from the disability lobby.
