How can you say stuttering is incurable…

How can you say stuttering is incurable… I’m wondering how you can say stuttering is incurable.. there’s a whole bunch of ex stuttered in this sub Reddit that have beaten their stutter including myself but you guys just chose to ignore that fact. Even when they give you tips on how they beat it you chose to ignore it and continue spitting non sense and become so negative. I get stuttering held you back from so many opportunities and have defeated mindsets but try to be hopeful and do some critical thinking when someone tries to give you tips on how to beat it. Just my two cents
