So the fact that the show is displaying a common and pervasive learning curve for hearing people when first exposed to deaf culture for the first time, is a bad thing? Yizuman is angry that the show is realistic?
I know this idea is completely out of left field, but might it just be possible that they are showing the hearing family as completely clueless, so they can, over time in a natural progression, show them growing and learning? (And along with the family, the clueless hearing viewer also learns about deaf culture, and vicariously works through the "culture clash," so when they actually encounter deaf individuals, they have a realistic frame of reference that actually sticks in their mind?)
