Why do deaf people consider alexander graham bell to be the "boogie man" of deaf culture?

Bell, along with several other well-known people, felt that deafness should be eradicated from the face of the earth. So rather than teaching (or allowing deaf students to be taught) sign language, he preferred to make his deaf students learn to read lips and use verbal speech rather than signing.
