A stutterer is actually thinking twice as hard as everyone else because on top of thinking and speaking, they're always planning--and changing--how to get words to come out of their mouth correctly.  16 years ago, during Biden's first speech as VP candidate, he called his friend, co-worker, and running mate Obama "Barackal Bama," "Barack Obaman," and "Barack America." See dutytowarn on X for posts and responses by medical professionals including psychiatrists, dementia experts, aging experts, and those who work with patients in those categories. Also, the ReallyAmerican YouTube channel had an eye-opening segment with a stuttering expert who also has a stutter.
