Political correctness
The social model of disability encourages identity first language (Sarah is disabled) and is not just preferred by most of the disabled community but is also part of the social model of disability. The social model of disability invokes (rather than erasing as medical model does) the idea that disability isn't just about limitations within daily life but also acknowledges that most of what creates "disability" are the social and infrastructural challenges faced, such as inaccessible housing, sidewalks, and elevators.
