To replace the phrase "learning disability", as currently applied as a generic term for a certain group of people, with more appropriate terms, such as "physically disabled".
Why does this idea matter?
The phrase "learning disability" is applied willy-nilly to many people who have a wide range of disabilities, regardless of whether their individual condition affects their ability to learn. In short, it suggests these people have limited knowledge due to an inability to learn. This is not always true and it is a label that some people can well do without. Often it is the rest of us who are at fault for not making the effort to understand what is being communicated to us by folks who have no problem (ie disability) with learning.
