When you fight your stutter you fight yourself. You're telling yourself a bonafide part of you is wrong and bad and needs to be eliminated (you can't just eliminate and stop stuttering). Accepting your stuttering doesn't mean you can't work on it to make it easier or less struggled, but you can't have some stuttering be ok and other kinds be not ok. It has to all be ok or none of it is, otherwise you're still just chasing the equivalent of fluency. Now some people have completely changed how they speak in an effort to curb their stuttering and have greatly reduced their stuttering and are happy with their choice. But most people don't want to change such a natural part of who they are and even those who try often come up short. The fluency shaping success stories are few and far between for a reason, It's a really limited option imo. And blocking is kind of the opposite of pure stuttering, it's a learned avoidance behavior (usually subconscious). Stuttering in it's pure form would be how you stuttered as a kid before you even new about it, your words would just bobble out when they did and that was that. Without any fear or shame or even thought.
