uhhh and your point is? It's natural a fairytale from Germany hundreds of years old would describe people as they looked. Disney cast a Latina as its most recent Snow White. And a black girl as the Little Mermaid. But it'd be a shame if your voice went unheard in the beauty standards debate
"Fairest" means "whitest", does it not? It's a fairly objective assessment.
Of course, the queen might've implied beauty. I imagine she'd be upset, if the mirror answered "Mark Zuckerberg".
