While we don't have any problem with the term disabled, I can see some advantages to the "people first language" and try to use it when I can - but I agree it's often way more simple/clear to say "disabled", "blind", etc...
The advantages are :
- Including temporarily disabled people (maybe more in french than english). If you break your legs and spend a few months in a wheelchair, you might not feel legitimate to use the term "disabled" in comparison to someone who has never been able to walk and suffers more from it. I'd also add my personal story: I suffer from chronic pain that is very incapacitating in my life. I don't feel legitimate when I call myself disabled. It's not temporary, but it's not as clear as blindness etc... Using people-first language feels more right.
- Including more person means reducing stigma and reducing the gap between abled/disabled.
- Not letting that disabilty define you as a person. I am not disabled, I am Sunderw, a complicated person with many different aspects.
That said, it should definitely not be a dictate because it only serves to divide more. Also, I had never heard the term "differently abled" which could sound almost sarcastic when employed to speak about someone in a wheelchair for example.[Edit: formatting]
