What is Wrong with the Use of these Terms: "Deaf-mute","Deaf and dumb", or "Hearing-impaired"?

20th Dec 2006

Deaf and hard of hearing people have the right to choose what they wish to be called, either as a group or on an individual basis. Overwhelmingly, deaf and hard of hearing people prefer to be called "deaf" or "hard of hearing"

From the National Association of the Deaf website. It makes me wonder about other terms I use (or read) like "Vision-impaired".
