*Added to that: the US gatekeeping on support animals is having to be reviewed, not just because people's choice of animals became unexpectedly challenging and impractical in all situations, but because they discovered that inevitably, there will always be humans who see a personal advantage and will take the piss.
In this case, the US authorities are finding that many people are using the useful phrase 'it's my support animal' to take their pet wherever they like.
The side effect is inevitably that those who need support animals, fought to open these doors, did not push the system to breaking point and would have used it responsibly with properly trained animals, are now encountering services and provisions and a general public that has become wary, cynical and is closing doors again, throwing inclusion into reverse.*
I read "Island" by Aldous Huxley relaxing after finishing my A levels.
It taught me that even in a perfect society human nature is such that some selfish bastard will soon turn up to exploit it, usually for their own financial gain, and ruin the previously perfect set up.
Age hasn't given me any reason to change my opinion, though maybe the book is due another reread.
