The world simply must continue to operate in a uniform fashion for the majority.
If it doesn't, the world descends into utter chaos (which it kind of is on its way in the UK)
It translates to:
Person with mental health problems "I need extra time for my exams "
Person with ADHD: "I need frequent breaks during my exams"
Person with autism : "I need to be isolated in my own room for my exams"
Person who prayers frequently : "I need a break from my exams to pray "
And it goes on and on.
Until you get 28 out of a class of 35 with various special treatments and the gullible 7 who struggle on and play by the rules (whilst getting ignored ) who eventually will think "fuck this, What's the point. Might as well say I've got anxiety"
(I've suffered with my mental health. Very likely have undiagnosed ADHD - but I never expect the world to adapt to me) i have no choice but to adapt to the world. It'd be ludicrous to think the world owes me anything.
Reasonable adjustments are very much warranted in a civilised society. But the clue is in the name: reasonable.
