Even complete confidence and uncaring isn't enough to achieve total fluency for a stutterer. It will definitely raise fluency a lot, don't get me wrong. But it doesn't get rid of a stutter, like on a foundational level. The stutter is still there. But yeah, ideally this is the way you wanna go. It takes a lot of time and mindfulness and avoidance reduction therapy. But we're always preaching those things, lol.
