As a legally blind person, don't be offended on my behalf.

All humans are imperfect.

They're lacking. If most people have five senses and someone has less then they're lacking.

“Can’t see fully” honestly sounds much much worse than “can’t see perfectly”. I am not blind, but I certainly can’t see perfectly. Both are pretty stupid ways to describe blindness.

What’s respectful is describing disabilities accurately and still treating the people who have them like valid human beings who are as valuable as everyone else. Not treating them like fragile children.

Great, more pointless words to be careful about. Have you run this by any blind or deaf people? Do they care in the slightest about this? I'd imagine most wouldn't give two shits which you used as long as you're not being a dick about it

Is this a joke?

Why don't we let the people affected by this define the verbiage used to refer to them?

Ian Dury and Chaz Jankel wrote the song "Spasticus Autisticus" back in 1981 about Ian's experiences as a person who was disabled due to polio as a child. He also viewed 1982 being deemed the International Year of Disabled Persons as being patronizing. The BBC and many other UK radio stations banned it from being broadcast.

In 2012, it was broadcast to a worldwide audience as part of the opening ceremony for the 2012 Summer Paralympics.
