Person-first terminology has been under debate since the 1990s[1][2]. The consensus among professionals (I just now spoke with a clinical psychologist Ph.D student who specializes in ASD research) is to use "individual with ASD/autism". Academia disagrees with you[3].
To be clear, if you would like to be referred to as an "autistic person", no one should have a problem with that. Similarly, you should not have a problem with the majority of people with autism preferring "person with autism". This means you should stop referring to this language as "pretentious, SJW-inspired nonsense".
