I think ELI5 means that you simplify a complex issue so that even a small kid understands it. In this case there is no need to simplify anything, just explain what a term actually means without assuming reader understanding nuances of terms used. And I still do not quite get how ELIA can be considered hostile, but given the feedback, maybe I avoid it in the future.
Saying "explain like I have <specific disability>" is blatantly inappropriate. As a gauge: Would you say this to your coworkers? Giving a presentation? Would you say this in front of (a caretaker for) someone with Autism? Especially since Asperger's hasn't even been used in practice for, what, over a decade?
> In this case there is no need to simplify anything
I don't see how this is a response to anything I've said. They're speaking to other humans and the original use of their modified idiom isn't framed as if one were talking about their own, personal disability.
