Well..she spoke her mind. I give her that, usually people keep it to themselves giving an impression that they do not actually feel. I'd rather people be more upfront. Stuttering is just another variable in how people perceive you. It puts off some people but not others, an unfortunate reality. You will never be attractive to everyone. It sounds like you're doing pretty well. I still feel crippling anxiety when doing presentations, and I cannot imagine leading a workshop in front of a group. Good work mate. Anyways, forget this moron. She read you wrong. Look for someone else.
