Some of these seem like legitimate improvements. A lot are inconsequential (e.g. "homeless person" vs "a person without a home"). But some are genuinely degrading our ability to communicate. E.g. "paraplegic" and "quadriplegic" should both be replaced with: "person with a spinal cord injury, person who is paralyzed" But this lacks the old term that distinguished paralysis below the waist with paralysis below the neck. A non-powered wheelchair is only going to help the former. Not to mention "person with a spinal cord injury severing the nerves to their legs, but not their arms" is a bit of a mouthful. If only there were a pair of words, perhaps using the roots to denote 2 and 4, that could convey these two things more concisely...
