I think laziness plays a part but I also think there is something else going on with some people
There is a certain pettiness ... sort of "Why does she get that ? Why can't I have that ? She gets to do that. I want to do that".
At the risk of starting a(nother) massive bunfight, I would suggest that the current "thing" (although I recognise it from the 1980s) of "self identifying" doesn't help in every situation. Quite a few BB abusers will have the attitude "well, I don't actually have a Blue Badge, but I 'feel' disabled, so that's OK".
It's a shame, with our mania for -only shortlists in politics that there isn't a disabled-only shortlist.
I wonder if FDR would have become president in 2016 ?
Personally I'd like to see a criminal law concerning abuse of facilities specifically provided under the DDA legislation. Very, very simple. If we can pass laws requiring a man to give the police 24 hours notice before having sex, it should be trivial.
Maybe a "Europeans with disabilites" act ?
Or at the very least, calling out politicians on the reality, rather than the rhetoric.
