You post is needlessly aggressive. I hope you weren't actually trying to be a total dick. Next time, take the time to put some thought into your post. Now, on to the content of your post. Where is your evidence? There is a shit ton of evidence that indicates stuttering has physiological and neurological roots. Psychological aspects may exacerbate stuttering, but they do not cause stuttering. However, I do think that there is an important point in ideas like these. However, they're often hidden in a variety of logical fallacies. So, make your point again. And actually make it this time.
