Hm, I honestly cant think of any other impediments now, but yes. Being cross eyed or anything like that is extremely taboo to bring up. Mainly adults yes, kids will always be kids. But if kids laugh at stuttering in the presence of parents or similar they will get talked to pretty harshly. Have some downsides aswell though, as nobody actually talks about stuttering and pretends its not there. So many people have questions about it that they dont dare to ask. Like "do you stutter in your mind" lol.
