@anonicus @Plutonium_Pity there is no evidence that Hellen Keller "said" or did anything under her own power. The prevailing theory is her "aide", who was interpreted for her, just said whatever she wanted.
Her aid was from an affluent family and coincidentally Keller's thoughts and opinions on matters of the time were the same as the affluent family.
Tl;Dr Hellen Keller was deaf and dumb and her aid spoke through her
