I agree. I spent years disclosing publicly, being okay with stuttering in most situations, and getting over the stigma. I kept that mindset but then added in other things like joint Toastmasters, taking singing lessons to work on diaphragmatic breathing, Alexander technique for posture, speaking in super loud clubs, etc etc etc. All do these drastically improved my speech. But he seemed to be against encouraging the group to try these tactics out. He thought it was strengthening my shame.
