I agree about HR! What an annoying term. But, unlike "the r-word", which has lots of history of being used as a direct insult and slur meant to be hurtful, "disability" has quite some time of history as use for political organizing and as a political identity. So while I would actually describe myself as having some physical impairments (such as not being able to walk much) I also would say I am disabled, as a social and political identity. No matter if I mean something different by it than people might think as they use the word to describe me, because it is a point of struggle. Hope that makes sense. It is super interesting how and why people shift the meanings of words!
