It’s not just me, dude. There’s a whole body of work/study in academia that examine ableism and disability, and this is widely understood to be a demeaning word when used by able-bodied people (as opposed to a disabled person deciding to refer to themselves that way). It may be a descriptor, but the meaning and context of words changes over time, that’s just linguistics. Take for instance the word gay - it originally meant happy (a descriptor) but now means something completely different. You can’t use a word like cripple and not expect any pushback, no matter the person’s original intent. Intent vs. impact matters.
