Can someone explain why we need another new word? I understand that it's to keep me from being a reprehensible person because of some insensitive utterance that might escape my lips. Does anyone with autism honestly care?

Can someone please define neurodivergent for me so I understand why this term is necessary in journalism?

I know I can Google it, but the search results and info boxes from the pangoogleopticon, on a question like this, will make my skin crawl and will certainly check any and all boxes required to keep the crazies from attacking. I am genuinely curious what this term accomplishes...

(If anyone takes the time for a thoughtful answer, I'd like to say "thanks".)
