For people who happen to have considerable trouble remembering names and retreat to pronouns to try to remain moderately functional despite their disability, non-obvious pronouns are a nightmare come true.

Now we get to have all the social anxiety that we used to have about names, but about pronouns too! Oh boy! We were so devastated by not having another way to give our lives more stress, tension, and the fear of being canceled for accidentally dogwhistling a neo-Nazi agenda!

Indeed, in more severe cases, people have resorted to pronouning names: https://www.nytimes.com/2019/05/30/style/trouble-remembering-names.html

So--sorry, Steve, but if you think liking high-convenience pronouns is a thing to distance yourself from, you've got yourself a very ableist outlook there.

Like names, it should be best-effort, with a lot of understanding for failures because not everyone has the same capabilities, and failure doesn't necessarily indicate disrespect.
