Heyo Rob,
Thanks for clarifying. I do recognize a difference between using a term as shorthand versus using a term in a contemptful way, which is why I separated the thoughts into different sentences. But I do feel it’s a slippery slope from allies using a term that got embraced to enable self- and in-group-identification, versus using a term in an ambiguous way with a heterogeneous audience (e.g., “Hyperbolic Aspies”).
Now, I’ve gone and checked my intuition, and can’t find any definitive evidence that “aspie” has crossed over from being benevolent to being a slur. But I have found enough evidence that other people have also had the same concern. 2013. 2012 2012. 2007 (the last more credible as it was in a support community for Autism/Aspergers.)
Now that the term Asperger’s has been abandoned as a medical term (like imbecile, moron, idiot, and retard, before it), the term will be defined socially and culturally. Given that “sperg” is already a slur descended from Aspergers that some folks use as shorthand for behavior they don’t like, it’s a fair bet that “aspie” is also at risk to slide in that direction (yes, I consider the glacial shift of language and linguistics to be a spectator sport. One of the many things that I’m pedantic about).
Speaking of pedants, and the definitions thereof: a defining feature of pedants is being annoying. And, I use “asshole” as shorthand for anyone that’s being annoying, because I’ve never seen anyone stand up to reclaim the term of “asshole” for their more positive use.
tl:dr one could say “pedants vs. literalists” with no loss in communication.
Signed,
Truly
A proud pedant and asshole on this topic.
