You don't need to respond to every comment directed at you. We stutterers have very high sensitivity towards what others say about our speech - So much so that we start obsessing over it. we dont really need to. If a crow is cawing in your ears as you pass by, do you feel the need to answer back? If a dog barks at you as you're walking by, do you feel the need to barkback? The answer is no. You might be the best dang orator in the world, but people will find something critical to say about you. You might speak like Obama, but someone will criticize you all the same. So, stop caring so much about what others say.
