I mean… didn’t you just answered your own question? Are you trying to understand how phrases like that are coined in the first place?

How is that ableist? It was “coined” by Horatio Nelson who himself was blind in one eye and ignored an order from his superior officer by raising a telescope to mockingly “look” at the signal flags of his superior’s ship while saying that he quote, “had the right to be blind sometimes”.

If you’re in circles where people are preformitively picking apart every single phrase known to man then the answer is ignore it.

This sort of thing almost 98% of the time happens online. No one is going around real life and getting mad at people saying phrases like that, unless said phrases include slurs or are egregiously racist, sexist, etc.
