Pet peeve: the way speech differences are given subtly ableist names.
I mean... "lisp"? "Rhotacism"? Come on!! At least let the people affected choose what to call it! Y'know, like... maybe something they can easily pronounce?
Can you imagine if we did that to the ableds? Replace some everyday phrase of theirs with something they literally can't say?
Like... what if we decreed that nobody can ever say "I'm going to go grab some lunch" anymore... now you have to say "everyone deserves to have all their needs met even if they don't work."
Instant chaos!
