In my university Library, dyslexic students don't have to pay any fines because the library system is confusing to them.
As if other students are perfectly capable of using the system and never get confused?
And you're at university, surely at this level if you're fine with organic chemistry or Latin history you should be able to get your head around a library system?
I think there is an overlap. There are people who are genuinely dyslexic, but there are thousands of people who are just a bit poor at spelling and have grabbed the label to suit their needs.
My Dad is quite clearly dyslexic. Left school at 15. Our house is filled with hundreds of history books and a massive passion for British History, he makes fantastic analyses and recalls facts that even astound me as a university student. Yet he asks me how to spell words like 'indicate' or 'genuine'. He's obviously not stupid.
