Some stutters have serious problems with stutter and can hardly say their name. There are a few things more fundamental in this life than than speaking and communicating. Imagine every single time you want to speak opening your month and possibly stuttering. Just because you want to go possibly die for your country, while brave and respectable. Doesn't give you the right to tell others what they experience isn't real. You have no idea. Facing your problems every single day no matter what is bravery too.
