I'm seeing a lot of proclamations that there should be no exceptions to describing your images or that there's no reason to interact with any that aren't described.

I know these mean well, but they are themselves ableist.

Disabled people know that access needs can clash. I benefit from described images, but I know some people struggle to write them because of their own disabilities.

And that's okay! The culture of image descriptions is great here but it should never be absolutist.
