Beyond Silence (Jenseits der Stille) Reviews
Lara's parents are not deaf and dumb, but just deaf. They are not dumb and are very expressive. Using sign language does not make them dumb. Only an idiot would say that. The sign language they use is not International Sign Language, but German Sign Language. Another idiotic label of their sign language!
The problem between the father of Lara and his sister does not originate from sibling rivalry, but from the unjust punishment he received from his audist father when he laughs out loud at the odd facial movements of a singer during a musical performance. The prejudices that this family has are not locally bound, but are widespread in countries all over the world. This is called audism, a mindset of hearing as the ultima ration of human existence, from which prejudices and discriminations against deaf people emanate.
