Of course I'm aware of it. But redefining well-known terms is a sign of groupthink, common among activist group. By pretending words mean a whole new thing, we can identify the in group, and humiliate the out group. I won't participate in that hallucination.
A disability is when you have less ability than everybody else. We can mitigate that by addressing {everything you list above}.
It's created large amounts of social change. American disability law derives from it, for one example.
Here's a cite from UK goverment mentioning the social model: https://www.gov.uk/government/publications/2010-to-2015-gove...
> We encourage the use of the social model as a way of understanding disability. It says that disability is created by barriers in society.
> The barriers generally fall into 3 categories:
> the environment – including inaccessible buildings and services
> people’s attitudes – stereotyping, discrimination and prejudice
> organisations – inflexible policies, practices and procedures
You probably need to be aware of this, because not being aware of it creates a risk if you ever have any management role.
