You obviously have good intentions but unfortunately there's not much you can do to help other than be nice when you encounter someone that stutters. Having a stutter and occasionally stuttering are different. The latter occurs when people are nervous when public speaking so you can probably help those people. But the former is a speech disorder that has something to do with how your brain processes speech. Thats what all of us on this sub have and unfortunately not much can be done to fix it. But it is always nice when people seek to learn more about stuttering as often we are judged as being nervous when in reality were not. I think you might be confusing the 2 cases as most people do.
