This guy, in the essence, teaches us to hide our stuttering. Pause for a moment to think, what kind of an effect hiding something that's a part of you has on your mental health and wellbeing. With stuttering, the biggest problem isn't the stuttering itself. It's how the people around us respond to it. Many don't simply know what stuttering is all about, and because of this they can react in various ways. There really isn't anyone else but us to educate the world about stuttering. I think we should do the exact opposite of what he's saying: not hide, but instead live our lives to the best we can while speaking with a stutter. When you stop hiding, the stress and fear of speaking also start to go away, which will have a positive effect on your speech.
