Not only he wanted to take away their schools, their organizations, their newspapers, and any form of communication between deaf and deaf: he wanted to ban any form of socialization amongst them, including banning deaf-deaf marriages.
And his mother and his wife were deaf, btw, so he was familiar with deaf people, which makes the things look even worse, as he had no excuses. What he said about deaf people wasn't much different from what Hitler wrote in his "Mein Kampf" about some races, seriously there are many similarities.
Oh, and he was (and still is, by many) considered an american hero, as the inventor of the telephone:
inventor my ass, he didn't invent a fuck: Meucci invented the telephone, Mr. Bell STOLE his materials and filed the patent taking advantage from the fact that Meucci was so poor that he couldn't afford the $250 needed for a definitive patent, so he filed a one-year renewable notice of an impending patent: but three years later he could not even afford the $10 to renew it.
Here comes mister Bell, files a patent for a telephone, becomes a celebrity and makes a super-lucrative deal with Western Union: the rest is history.
113 years after his death, the US Congress recognised the poor italian immigrant Meucci as the inventor of the telephone rather than Alexander Graham Bell.
