I used to think a lot like that, still do sometimes like: Dude, you can speak anything you want without stuter, why don't you? It's easy for you, you don't have a problem. But then i realized that everyone has insecurities and reasons or excuses, mine excuse for not doing things was stuttering, a fluently person would have another excuse. You can say that stutter is a more ''real'' reason for anxiety or worry. Fair enough and understandable, but for ME, that's just an excuse because, other people have so much worse than us and their still do it. Everybody has an excuse i guess
