But come on, what kind of a society are we living in where you can't call people for what they really are and nowadays have to come up with new warm + fuzzy words to describe them?
Personally, having gone through high school in the late 80s/early 90s, if I wanted to be "hurtful" to these people can think of several really derogatory terms that could have been used instead of 'deaf & dumb' (and no I wasn't a bully, but the stuff we said and did on the playground and in the classroom would get all of us expelled in todays education system. but I digress.)
