I mean Iron Mike has a lisp and he gets by pretty fine. Atleast he can express himself without having to contort his face, blink rapidly or block for seconds unend. I'm not sure he deals with the fear and anxiety of being unable to mention his name too. He does not fear making calls. Yes, some people mock him but he doesn't struggle to talk like we do. In our case, we struggle to talk and get mocked too, sometimes we come across as being timid and lacking confidence. I will take a lisp everyday of the week over stuttering.
