Often times, the most difficult part of solving a problem, a social problem or others, is about framing it in the right way. If you are dealing with a situation, but you misidentify the source of the conflict or barrier, then any solution becomes impossible, or at least incomplete. The same is true of discussion of disability justice and issues of equality.
Many of the conflicts that arise between abled communities and mindsets, and disabled ones step from different framings of the problem. While many different constructs and models exist, the two mainly accepted ones are the Medical Model and the Social Model.
