If the job those animals are applying for involves climbing trees, then that is a perfectly fair selection. Equal opportunity does not produce equal outcomes.
As for autists not making it in a normie world, society is "set up in a way" that caters to the needs of the market. Autists could certainly thrive in the world - computer autists managing computers, farming autists managing farms, train autists managing rail transport, cleaning autists managing janitorial work, etc. - but they'd need to produce something of tangible value to the marketplace, rather than just sitting around drawing trains all day.
If you flip things around, put the cart before the autistic horse and make a society that unfairly caters to the needs of autists rather than the pragmatic needs of the market, then nothing will get done, society will collapse, and autists will starve to death in front of their now-internetless computers, still deseperately trying to access their favorite DA pages.
