I mean this is true but you could apply it to any disability. If someone was deaf it would be accurate that they wouldn't be able to hear to save someone's life if they needed to, I don't think a deaf person would be hated by everyone for that. Same with a blind person, if they can't see in a crisis to save someone's life, it's not their fault. People would probably be less compassionate to someone who stutters though than someone blind or deaf because people for some reason seem to think stuttering is something you can control with "will power"
