You have probably noticed in posts throughout my Love Disabled Life blog that I often write "disabled people" rather than "people with disabilities." This is known as "identity-first" language and not "person-first" language. Identity-first language embraces the term (or label) of disability as being at one with the identity of who a person is. The same as a person would do if they were referring to themselves racially or ethnically. For example it is not common nomenclature to say "person with a Swedishness" (I, happen to be of Swedish heritage) You would say, Swedish person.
Disability pride is the open and vocal declaration, dare I say unapologetic, of one's disability identity. Those who are disabled and proud not only acknowledge they are disabled, but they embrace it as part of their being. It reflects much more of the social model of disability. That is, that the construct of disability resides in the environment, and not in themselves. People who are proud to be disabled aren't looking to be cured, fixed or appeased. Rather, they seek the same rights, access and freedoms that any non-disabled person is afforded.
