I somewhat agree with you and disagree. I think you first have to accept your stutter before treating it. As more and more evidence comes out, its evident that stuttering is a neurological problem. Instead of a magic pill, i personally think tDCS can be useful for treating a stutter. I imagine the brain as more of a muscle and the area involved with stuttering needs to be worked out. With tDCS, i believe it may be easier to activate that part of the brain.
