It might help if people educated themselves on people who stutter. Good article on stuttering by a stutterer interviewing Joe Biden

The Atlantic January/February 2020 (Emma) Alpern told me that she’s on a group text with other stutterers who regularly discuss Biden, and that it’s been “frustrating” to watch the media portray Biden’s speech impediment as a sign of mental decline or dishonesty. “Biden allows that to happen by not naming it for what it is,” she said, though she’s not sure that his presidential candidacy would benefit if he were more forthcoming. “I think he’s dug himself into a hole of not saying that he still stutters for so long that it would strike people as a little weird.”
