The vast majority of us on this thread who express a distaste for the phrase are neurodivergent ourselves.
And we are allowed to express both our opinion and our experience. It’s interesting that a lot of us have had similar experiences with the type of people that use the word, which suggests there could be some truth in it.
You don’t get to tell ND people that they’re not allowed an opinion in how they’re described. Those days are over.
Also worth pointing out that no stereotype is 100% true for everyone. I don’t know your or your DS. Maybe he fits the stereotype, maybe he doesn’t.
If he chooses to describe himself as neurospicy, that’s up to him. Might be worth him having an understanding of how it’s likely to be perceived by others outside his group though. Not to get him to change his mind, but because it could be significant in how he’s perceived.
Of those of us on this thread who intensely dislike the word and find it offensive, I can’t recall a single person who has said they tell others to stop using it. I certainly don’t. I may internally eye roll but that’s it.
You also could have made your point without using a derogatory slur. It didn’t add any weight to your argument and is just downright unpleasant.
Your DS will continue to describe himself as neurospicy. Many of us will continue to find it an unpleasant word. And the world will keep on turning with both things unchanged.
