"People with autism" carries a connotation that the person and the autism are separable. Given the deep, dark, nasty history of autism "cures" that's a very raw nerve, and stamping out that type of thinking will materially improve conditions.

Depends on if you’re talking to autistic people, or professionals who work with autistic people/their parents.

The latter group still tends to use “person with autism” and I think it’s more funny than anything but people get really pissed at people who developed this vocabulary without actually asking Autistic people what they thought of it.

I love the phrasing “person with autism” because it allows me to make a bunch of fairly accurate assumptions about the type of person you are, which is generally somebody who sees autism in a very paternalistic light. Why stigmatize the use of language where somebody self-identifies themselves as hostile to your interests and seeing themselves as being your woke saviour? What was that saying - don’t interrupt your enemy while they’re making a mistake?

Good point, weird constructed language can also be utilized as a filter to avoid hostile and/or paternalistic people. Weaponizing SJW language to fight bigots, I like it!
