I've never heard anyone say anything like this before .. it's interesting. I will say I used to stammer and get stuck (block) alot in my youth, but i was almost able to completely stop stammering by my mid-late teens; never been able to stop the blocks though. Even with years of practice and breath techniques etc. I usually never get pissed off at people's opinions, but what you said makes it sound like those with blocks choose to do it and instead of letting the stammer be seen we use the blocks instead like we're cowards or something. I can tell you people look at you like a fucking freak of nature when you block and from my experience , between the two, I've got more hate, laughter and looks disgust with blocking then stammering. You probably won't read all this, but if you do I hope you change your mindset about your fellow stutters and don't ever minimize the horrible experiences we went through or say we "chose" this or the other. It makes you sound extremely uneducated, foolish and as a person that has never had this speech impediment before. Smh
